The Evolution Deceit
The Language of Colours
Just as colours are important for people in making sense of their surroundings, so are they indispensable for other living beings to survive.
Living beings have a "colour language" that works according to the light and the systems of perception they possess. Different colours bear different meanings for every living being. In order to survive, every living being has to know the language of colours used in its habitat, because vital functions can only be controlled by acknowledgement of this language. So, how do living beings use this colour language?
First, the majority of living beings need the help of colours in order to find food. Second, the colours that exist on formations such as skin, scales and fur play an important role in the continuity of life due to their characteristics of absorbing or diffusing heat. In addition, living things use their colourings to protect themselves from their enemies. Owing to colours that harmonise with their habitat, they can camouflage themselves and hide from their enemies. Alternatively, their colourings and patterning may pose a discouraging image for their enemies. Colours also help animals to recognise their mates and chicks. A mother bird, for example, understands whether her chicks need food or not from the colours of their gapes. Similarly, the chick recognises its mother in this way and understands that the food has arrived.16 As seen in these examples in nature, living beings need to know the meaning of colours in order to survive. In order to attain this knowledge correctly they need to possess proper systems of perception.
If they did not have these systems, they would not be able to perceive their surroundings properly or carry out their vital activities. They would not be able to recognise their foods or discriminate their enemies. Therefore, in this latter case they would stand out from the outside world and be an easy prey doomed to death.
Surely, no one can claim that such sophisticated systems might have come into existence by coincidence. Every system, every harmony, every design, every program, every plan, every balance must be created by a designer. There is certainly a higher will and power that has perfectly placed this harmony in living beings and the habitats in which they live. The owner of this power encompasses both the surroundings and the living being itself and the systems it uses with a higher knowledge. The owner of this power is Allah, Lord of the worlds. When we examine living beings, we see how skilfully they employ the language of colours.:
Here are some examples of the language of colours, which has such an important place in the life of living beings
Camouflage is one of the most effective defence tactics that animals use. Self-camouflaging animals are under some kind of protection because of their body structures, which are created in great harmony with their habitats. The bodies of these animals are so harmonious with their environments that when you look at their pictures, it is almost impossible to tell if they are plants or animals, or to distinguish an animal and a plant present in the same environment from each other.
The living creatures that adapt their colourings according to the environments in which they live have always attracted the attention of scientists. Research focuses on finding an answer to the question of how a living creature can look exactly the same as a creature that is of a completely different structure.
Have you ever thought, for instance, how a frog, which, while walking in the garden, you took for a leaf, and then at the last moment skipped a step and avoided stepping on it, has it come to possess these patterns and colour? Camouflage is a very important defence mechanism for a frog. The frog that is unnoticed in its environment easily loses its enemies.
While a pink spider on a pink flower can successfully take on the flower's different shades of pinks of, another member of the same spider species can adapt to the colour of another flower, for instance, a yellow one, when it climbs on it.
The seven heavens and the earth and everyone in them glorify Him. There is nothing which does not glorify Him with praise but you do not understand their glorification. He is All-Forbearing, Ever-Forgiving.
(Surat al-Isra': 44)
While someone is looking at a branch, thinking there is nothing on it, a butterfly may fly away from it all of a sudden. This butterfly, which looked exactly like a leaf down to the dry, autumn-withered parts a second ago, is a perfect example of the miracle of camouflage.
As will be seen in the following pages, the similarity of living creatures to the objects on which they rest prevents their enemies from noticing them. It is obvious that these camouflaging creatures have not made themselves, on their own initiative, look like leaves, branches or flowers. What's more, they are not even aware that they are protected because of these similarities. Nevertheless, they employ camouflage very skilfully in all our examples without exception. An insect having the same colour as a flower, a snake standing still as a tree's branch, a frog adapting to the colour of wet ground, in short, all self-camouflaging creatures are evidence proving that camouflage is a specially created defence tactic.
No living creature can perform such a task on its own or by coincidence. Certainly, He Who bestows upon living creatures the ability to camouflage themselves, and places the chemical processes in them by which they can carry out this colour change, is Allah, the All-Knowing, the All-Wise.
Camouflage techniques of reptiles
What does a reptile do to protect itself against its predators in the wild? One of the easiest ways for these slow-moving creatures is definitely to conceal themselves. The best method of hiding is adaptation of the creature's body to its habitat. Colours and patterns usually serve as a lifesaver for many animals. For example, in the forest it is almost impossible to distinguish a Rhino Viper, a kind of tropical snake living in the rainforests of Africa, due to its skin being covered with blue, red, yellow, black and white geometric patterns. Interestingly, the colours of the snake match the surroundings in which it lives. This one-to-one relationship evokes some questions in the mind. How did these colours, which harmonise with the environment so well, emerge? Is it possible for this to have happened by chance, or to have been produced by the reptile itself?
Certainly, it is not possible at all. It is impossible for a reptile first to analyse its environment, then to decide what kind of changes it needs to make in itself, and finally to determine a colour and pattern. Furthermore, it is totally illogical and unreasonable to claim that it might have set up a system in its body to carry out the chemical reactions that are necessary for such a change.
Even man, the only living being endowed with reason on earth, cannot change the colour of any part of his body. He cannot establish a system in his body to bring about such a change. In this case, there is only one explanation for the perfect resemblance of the colour of the reptile to the colour of its surroundings to such an extent that even the shades do not differ. An infinitely superior possessor of wisdom has designed this living creature. This design belongs to Allah, the Almighty. Allah is He Who knows best the needs of every living being.
The Most Famous Camouflaging Reptile: the Chameleon
Have you ever seen a chameleon changing its colour according to its surroundings? This is indeed something worth seeing. The chameleon has such an exceptional ability to camouflage itself that its deftness astonishes everyone. Although many other reptile species have the ability to change their colours, none of them is capable of doing it as rapidly as chameleons.The chameleon uses red and yellow colour carriers, blue and white reflector layers and most importantly "chromatophores", skin cells that respond to variations in heat, light and the animal's mood.30 If you put a chameleon in a very yellow setting, for example, you would see that the colour of its body instantly turns yellow and adapts to its surroundings. What's more, chameleons adapt not only to a single colour, but also to multicoloured substrata. The secret of their achievement is the colour cells, lying under the skin of this master of camouflage, which magnify and swiftly change place to adapt to the environment. Could a chameleon make such a perfect adaptation on its own? How do these creatures indistinguishably blend in with the environments in which they live, while even the most skilful artist has to work for hours to obtain the equivalent of a single natural colour?
It would surely be unreasonable to claim that a chameleon could perform such an act of its own volition. It is certainly not possible for a reptile to determine the appearance of its body, nor to place a system in its body to change its appearance. It would be just as nonsensical to claim that this creature has control over all the cells and atoms in its body, that it is capable of making whatever change it wishes on them and produce the required pigments. It is totally inconsistent and meaningless to claim that such an exceptional ability has come into being by chance. No mechanism in nature has the power of producing such perfect skill and granting it to the being that needs it. Just as all other living beings on earth, Allah also created chameleons. Allah demonstrates to us the uniqueness of His artistry in creation with these examples. Allah is the Almighty, the All-Wise.
Everything in the heavens and the earth glorifies Allah. He is the Almighty, the All-Wise. The kingdom of the heavens and the earth belongs to Him. He gives life and causes to die. He has power over all things. (Surat al-Hadid: 1-2)
Colour Change According to the Environment
Do living creatures only make use of colour to protect themselves against their enemies? Definitely not. Some animals protect themselves also from cold and heat by means of enzymes giving colour to the hairs covering their bodies. In animals that live in cold regions, the hairs covering the tip of the legs, ear and nose, which are the most sensitive parts of the body, are dark coloured. Dark coloured hairs provide more heat energy for animals thus helping them to warm easier, just like humans who try to benefit from the sun better by wearing dark coloured clothes in winter. Colour change is very common in land animals. For example, in summer, the fur of the northern fox turns white, because their body temperature is high. In winters, however, as it becomes colder, their body temperature drops and a more suitable environment for the enzymes to work easily is provided. For this reason, in winters, the fur of the northern fox darkens. Rabbits, foxes, weasels, and polecats living in northern latitudes turn brown in summer and white in winter.
While some birds become completely white in winter months, they take on a new appearance in spring matching the colour of the ground and vegetation.
Living creatures make use of colour for varied purposes. Using it as a mean of warning is one of these purposes. In the following pages, we will give some examples of this.
In the creation of the heavens and earth, and the alternation of the night and day, and the ships which sail the seas to people's benefit, and the water which Allah sends down from the sky – by which He brings the earth to life when it was dead and scatters about in it creatures of every kind – and the varying direction of the winds, and the clouds subservient between heaven and earth,
there are signs for people who use their intellect.
(Surat al-Baqara: 164)
Colours in Birds
One of the most important features of the multicoloured feathers of birds is that they are lifeless structures. The reason why a feather maintains its colour exactly, even after it is shed, is that a fully developed feather is completely lifeless.
Rich colour diversity in birds is basically due to the presence of pigments in the feathers, which were stored during the initial development phases of the feather, or the light shifts which occur depending on the structural characteristics of the feathers.
Since these formations, which are made up of the substance keratin, are soon worn down by environmental conditions, they are regularly renewed. Yet, each time, the bird regains its colourful feathers. This is because the feathers of birds continue to grow until they fully reach the necessary length, and the characteristic colour and pattern of that specific kind.
Due to their different structure, feathers can have an appearance similar to that obtained by a glass prism breaking light into different colours. Colours that are formed through refraction of light in this way are brighter and more metallic than those that are coloured by pigments. The colours of these feathers shift from blue to green, and from orange to red. Generally, the green, blue, and metallic colours in birds are formed through the reflection and refraction of light. Yet, some of the colours of feathers come from pigments.39
There are mainly three kinds of pigments in birds. These are melanin pigments that produce black, brown or dull yellow, lipochrome pigments that produce red, yellow or orange, and carotenoids.
Blue, green and some other bright colours in birds are created by microscopic bubbles in the keratin of the feathers that refract the light. The feathers absorbing the full spectrum of light and only reflecting blue, on the other hand, creates the blue colour of some birds.40
Hormones also play an important role in colour change in birds. The colour difference between the male and female members of some species is caused by sex hormones. The different colourings and feather shapes of cocks and hens, for example, depend on the oestrogen hormone.
The colours of birds are important for their adaptation to their habitat as well as for male and female members' recognition of each other and the males' courtship of females in the mating season. In addition, pigments, which give colour to feathers, enhance the strength of the feathers, store energy coming from the sun and prevent harmful ultraviolet rays from entering the body.
Formation of colour in the wings of butterflies is quite interesting. The light is reflected through the scales on the wings of a butterfly forming colours which are "actually non-existent" but which display an extraordinary symmetry and beauty. We just said that they are "actually non-existent", you wonder why?
Butterflies are known for the beauty of their wings that have surfaces that are relatively much wider than their thorax. How, then, do these spectacular patterns and colours in the wings of butterflies come about?
Butterflies have a pair of membranous wings, which are in fact transparent. Since these are covered with scales of varying thickness, the transparency of the membranous wings goes unnoticed. These scales increase the aerodynamic qualities of the butterflies' wings, and give them their colour. The scales, which are so delicate as to fall from their places as soon as they are touched, have sharply-pointed ends sticking into the wings of the butterfly. In this way, the scales remain attached without falling off. Each of these tiny scales, which seem like overlapping shingles on a roof, take on a colour either by chemical pigments or by its structure which refracts the light falling onto it into rainbow colours as does a soap bubble.41 In addition, laboratory research has shown that different colours depend on different chemical substances. The by-products of a colouring substance called pteridine, for example, create the pink, white, and yellow colours that are commonly seen in butterflies. Melanin, which is a very common colouring substance, exists in the black spots in the wings. Interestingly, the colours in the wings of butterflies are not always as they seem to be. For example, green scales are in reality a mixture of black and yellow scales. Recent research conducted on butterfly wings has demonstrated that pigments are synthesised in the scales and that the enzymes necessary for melanin production lie in the upper skin of the scales.
Colouring substances are not the only cause of these highly volatile colours in butterflies. The structure and the order of the scales on the wings of the butterfly cause various tricks of light, such as reflection, refraction, and finally the formation of colours of dazzling beauty. For instance, Stilpnotio Salicis butterflies have semi-transparent scales, which contain bubbles. Although there is no colouring substance in these scales, the light passing through the scales give the butterfly a satin-like appearance.
The surface of the scales on the Argynnis butterfly's wings is unbelievably soft, which creates silvery reflections. In some butterflies, the different arrangement of two overlapping rows of scales may also create different reflections of light, for example, causing a butterfly to look blue instead of black or brown. When we examine the structure of butterfly wings even by considering their colourings alone, we come across lots of wonders. The existence of such an extraordinary beauty is undoubtedly evidence of the exalted might and endless artistry of Allah, Who has created all these.
It also must be stated that besides their being created as adornment, the colours and patterns on the wings of butterflies have many other crucial functions for these creatures.
False Eyes of Butterflies
In many butterflies, there are round dark-coloured patterns that remind us of the eyes of a large creature. These eyes, which again consist of coloured scales on the wings, embody a most important defence mechanism for butterflies. Butterflies keep their wings closed when they rest. If they meet an enemy, or are disturbed by a slight touch, the wings instantly open, and large, bright, intensely coloured eyespots on the wing surface appear. In this way, the required message is delivered to the predator.
Camouflage of Butterflies
Butterflies' camouflaging skills are as impressive as their false eyes. It is as if camouflaging butterflies see the colour of the bush, make an evaluation of the environment, analyse it, and imitate the colour of the bush with the colours they produce in their bodies' highly effective systems. Another species, aware of the tastes of its predator, gives warning signals to it by imitating colours that repel it by suggesting that the butterfly would taste bad or even be poisonous. It is by no means possible for a butterfly alone to perform these acts. We can make it clearer with an example:
Suppose that you are trying to produce a colour in a laboratory. If you have little knowledge of this subject, you will not be able to achieve the definite result that you wish, no matter how advanced your laboratory equipment or facilities. Then consider trying to achieve the quality of colours such as those of the butterflies, which, by developing the same colours and patterns as the environment, become almost invisible. You would not be able to develop even a single meaningful colour. The situation being so, it would be certainly an unscientific and irrational approach to claim that this glorious system in butterflies has come into existence by chance free of conscious design. If there is a design somewhere, there is also a designer. The flawless design on the earth belongs to Allah, the Compassionate. What falls to people with reason is to reflect upon Allah's attribute of creating in detail. In Surat an-Nahl, Allah states as follows:
(He has made subservient to you) also the things of varying colours He has created for you in the earth. There is certainly a Sign in that for people who pay heed. (Surat an-Nahl: 13)
Black Spots that Absorb Light
In some butterflies, especially on the parts of their wings that are near to the body, there are large, dark coloured spots that consist of scales. These spots, placed on both wings symmetrically, have a very important function for butterflies. Butterflies make use of these spots in order to reach the body temperature that is required to fly. How do they do this?
Scales have the properties of modifying heat to minimum or maximum levels depending on their colours. We have all seen butterflies opening and closing their wings under the sun as if they are trying to find a certain angle. The black spots in their wings help those butterflies, which try to attract sunlight by this movement. A butterfly that needs to warm up its body opens and closes its wings so that the sunlight falls directly on these spots, and therefore warms up its body.
Butterflies that live in open lands exposed to sun have lighter colours while those that live in wooded areas have darker colours.
Some species of Lepidoptera butterflies have no scales on their wings, cannot reflect light, and so are transparent. Though it is possible to see these butterflies while they fly, it is almost impossible to locate them when they alight somewhere. This provides a perfect protection for the butterfly. Just as all other creatures, butterflies have also been created with the systems with which they can meet all their needs. Moreover, all these are interdependent systems in which one cannot exist without the other.
Like all other creatures in the universe, Allah created butterflies too with all the details they possess and endowed them with all the systems they need.
Colours of the Undersea
Life under the surface of the sea is very different from on land. All the features of sea-dwelling creatures are organised in such a way as to enable them to live in water in the easiest way possible. Humans cannot see in water as well as do fish, because the human eye does not have the features that would allow it to attain sharp eyesight underwater. The human eye does not have a lens system such as that of the fish, and is not spherical and hard like that of a fish, so it does not have as sharp sight underwater as the fish. It cannot allow as precisely as fish do for foreshortening of distances in the water due to refraction, as it cannot estimate the refraction of light in water.
Allah has created every living being with the most suitable characteristics for the environment it inhabits. Creatures living under the sea constitute only a small part of the examples of Allah's artistry in creation. Allah has no partner in creation and everything is under His control.
There is no other god besides Allah. Allah – He is the Almighty, the All-Wise. (Surah Al 'Imran: 62)
In the heavens and earth, there are certainly Signs for the believers. And in your creation and all the creatures He has spread about there are Signs for people with certainty. And in the alternation of night and day and the provision Allah sends down from the sky, bringing the earth to life by it after it has died, and the varying direction of the winds, there are Signs for people who use their intellect. Those are Allah's Signs We recite you with truth. In what discourse, then, after Allah and His Signs, will they believe?
Design of Colours in Plants
If one does not reflect, one cannot see the miraculous characteristics of the living beings around one. So long as one does not think about how a butterfly with its membranous wings flies, how the flowers one sees have such diversity of colour, how the top branches of hundreds of metres tall trees remain green, one cannot grasp the subtleties of these. Even the extraordinary artistry in a flower may not capture one's attention.
As we examined throughout this book, however, perfect artistry is clearly displayed in all living beings from insects to birds, from plants to sea creatures. Certainly this artistry belongs to Allah Who is the Creator of all living things.
Let us think about plants, fruits, vegetables, flowers, and trees. Plants, each having different colours, fragrances and tastes, are evidence of the artistry in creation of Allah. Each plant you see around you or know from books has colours and patterns that are exclusive to its kind. The reproductive process of each is different, the proportions of nectar they contain and their fragrances are all different. Let us think about roses. There are red, white, yellow, orange, pink, white edged, double-coloured, even roses with wavelike colours. Certainly, it would be great blindness for a man who sees all this not to feel admiration for and not to glimpse the endless might of Allah, Who is the Creator of all these flowers. In the Qur'an, Allah refers to those who fail to appreciate the evidence of the creation they see as follows:
How many Signs there are in the heavens and earth! Yet they pass them by turning away from them. Most of them do not have faith in Allah without associating others with Him. (Surah Yusuf: 105-106)
Have you ever thought about why plants are green?
As is obvious, the colours prevailing in the world of plants are green and shades of green. Chlorophyll is the main substance producing green. Chlorophyll, a very important substance, is a pigment contained in the chloroplasts scattered out in the cytoplasm of the plant cell. These pigments absorb light coming from the sun easily, but only reflect the colour green. In addition to giving the colour green to leaves, this feature also causes the fulfilment of a crucial process called "photosynthesis".
In photosynthesis, plants utilise sunlight, which consists of the combination of different colours. One of the most important properties of the colours in sunlight is that their energy levels are different from one another. This assortment of colour called the spectrum, which is obtained by the refraction of colours in a prism for example, has red and yellow tones at one end, and blue and violet tones at the other end. Colours with the highest level of energy are those colours at the blue end of the spectrum.
The difference in the energy levels between colours is very important for plants, because they need large amounts of energy to make photosynthesis. For this reason, during photosynthesis, plants absorb those sunrays of the highest energy levels towards the ultraviolet end of the spectrum, i.e. violet and blue, as well as the colours that are more towards the infra-red (heat) end of the spectrum, i.e. red, orange and yellow. Leaves carry out all these processes through the chlorophyll pigment existing in the chloroplasts.52
For a plant to photosynthesise, the energy levels of the light particles that are absorbed by the substance chlorophyll must be adequate. The process of photosynthesis begins when a plant, with the energy it receives from light particles, breaks the water molecules into oxygen and hydrogen molecules. Hydrogen reacts with carbon in the carbon dioxide gas to form the sap of the plant, which is essential for the plant to survive. In other words, the plant produces its own food. Unused oxygen, on the other hand, is released to the air. Most of the oxygen we breathe in the atmosphere is produced that way.
As a result of the process of photosynthesis in plants, they produce carbohydrates, one of the main food sources for other living things. The substances produced during photosynthesis are extremely important for plants themselves as well as for animals and humans, because plants are the main source of food of all living things on earth.
As we have seen, besides providing an aesthetic appearance, the green colour of plants is also extremely crucial for the survival of both plants and other living creatures. Allah makes the substance chlorophyll a cause for the nourishment of plants and the sustenance of all other living creatures.
How do the Different Colours in Plants Come About?
As mentioned before, the colour reflected by each object depends on the pigment molecules that object has. The basic pigment molecule in green plants is the substance "chlorophyll" as earlier stated. In addition to this, there are other pigments producing other colours in plants, and these different kinds of pigments form the extraordinary colour diversity we see in plants.
For example, in addition to chlorophyll, there are also carotenoid pigments in plants. Some of these pigments, which we have examined in detail before, are yellow and give colour to ears of corn, lemons, goldenrod and sunflowers. Other carotenoids are much more red than yellow; these are found in beets, tomatoes, roses, and carrots. Carotenoids are also present in green leaves. Then one might wonder: why do leaves not look red, yellow or orange but are mostly in shades of green? The reason is that the green of the chlorophyll is so strong that other colours cannot be seen.53
However, changes occur in the autumn. As the hours of daylight become shorter, plants stop making chlorophyll, and the strength of the pigments producing the colour green decreases, causing the green colour of leaves to fade. The carotenoids, becoming visible now, colour the leaves brown, yellow, and red. Also in the autumn, a group of pigments called "anthocyanins" form in the outer layers of certain leaves. These pigments, which are bright red and blue, combine with the others to give leaves the crimson and purple hues we occasionally see.54
Information about all the pigments giving colour to a plant is coded in the DNA of that plant. For this reason, a plant species bears the same characteristics no matter where on the earth. For example, everywhere in the world the colour of oranges is the same; their shape and the structure of their peels are the same. The colour of the transparent membrane, which lies inside the peel of the orange, and which constitute little sacs filled with orange coloured, perfumed sugared water, never change anywhere in the world. Bananas are everywhere yellow, tomatoes are red, and roses, violets, and carnations are all the same colours wherever they are. Wherever you go in the world, you will not see a naturally growing strawberry with a different colour. Everywhere in the world, the DNA of strawberries contains the characteristics that make them the strawberry we know. The colour, smell and taste of a strawberry are always the same. It is a unique, unparalleled order. Certainly, it cannot be claimed that such a system has come into existence by sheer chance.
The owner of this matchless artistry that prevails all over the world is Allah, Who has infinite wisdom. Allah has power over all things.
Have you ever thought how such diversity of colour comes about in plants although they all grow in the same soil and are watered with the same water?
In Surat ar-Ra'd, Allah draws attention to the fact that although all watered with the same water, different crops come out of the soil:
In the earth there are diverse regions side by side and gardens of grapes and cultivated fields, and palm-trees sharing one root and others with individual roots, all watered with the same water. And We make some things better to eat than others. There are Signs in that for people who use their intellect. (Surat ar-Ra'd: 4)
As Allah has drawn to our attention, let us ponder, by looking at the vegetables and fruits around us, how different crops come out of the same soil. For example, let us look at melons, watermelons, kiwis, bananas, cherries, eggplants, tomatoes, grapes, peaches, and green beans. When you peel the dark yellow skin of a banana, out of it comes a banana of a lighter yellow with its matchless fragrance. The red, green or yellow peel of an apple has a smooth sheen. Humans cannot imitate the quality of the taste and smell, an aroma particular to it, of its sweet juice.
Then, the question may occur to one: how do all those flowers, trees, vegetables and fruits have so many different colours although they come out of the same arid soil? This is evidence of the endless knowledge of Allah and His creating without any preceding model. It is impossible for man to create a new colour. All colours produced by people are only copies of the originals existing in nature. However, Allah is the Originator, and the creation of all the colours describing the living creatures on earth is His. Allah's artistry in creation is matchless. One of the names of Allah, the All-Powerful, is al-Musawwir – the One Who forms His creatures in different forms. Allah creates everything He creates in the most perfect forms.
He is Allah – the Creator, the Maker, the Giver of Form. To Him belong the Most Beautiful Names. Everything in the heavens and earth glorifies Him. He is the Almighty, the All-Wise. (Surat al-Hashr: 24)
The colours and appearance of all plants on the earth have been created in such a way as to appeal to the human soul. In fruits and vegetables, there is a matchless diversity of colour. On the other hand, when we think of flowers and trees we again see the same aesthetic appearance and diversity of colour.
There is also a totally unequalled colour and pattern design in flowers. Each of the hundreds of thousand kinds of flowers has been furnished with particular characteristics exclusive to its kind. Today, the perfumes, patterns and colours produced by men are all imitations of their original counterparts in nature. For instance, the purple colour of the leaves of violets, which are soft like velvet, and the smoothness of the surface of their leaves are matchless. Velvet fabrics are produced in imitation of the texture of violets but a similar quality can never be achieved.
With this approach, no matter what plant we examine on the earth, the conclusion we arrive at is that it is a perfect creation. Allah, Who has no partners in creation, creates plants for men with different tastes, fragrances, colours and forms. What falls to us is to reflect on the signs Allah creates and to be grateful.
