The Evolution Deceit
Hazrat Mahdi (as) is moderate of virtue and excellent of creation... HIS STEED WILL SHINE LIKE A FULL MOON. HE [HAZRAT MAHDI (AS)] WILL GO AT THE HEAD OF THE MOST AUSPICIOUS COMMUNITY. They are enfolded by Allah’s religion; they will seek to approach Allah with him... (Sheikh Muhammad ibn Ibrahim Numani, al-Ghaybah al-Numani, p. 171)
The hadith suggests that “cars” will be one of the technical vehicles available in the time of Hazrat Mahdi (as), and that these will have headlights and interior lighting. It appears from the information provided in the hadith that the headlights of Hazrat Mahdi’s (as) car will also shine brightly.
