After describing the general characteristics of infidels in their disbelief of Dooms Day and who were ridiculing it as stories of old, of which they and their forefathers were threatened, they demanded actual date of it, which is only known to God Who has held it in secrecy. None should insist on it. During Resurrection, when time for avenging the Prophet’s enemies, will come during the emergence of the 12th Light, there shall appear Dajjal, a Jew by caste and sorcerer by profession, born in the afternoon of Wednesday, in the time of the Prophet, six miles away from Medina, and one eyed and who started talking, having on his forehead, inscribed infidelity. The Prophet demanded evidence of his prophecy, upon which he demand of the Prop[he his Divine nomination. The Prophet cursed him. He has been spared until Resurrection and will be slain by Jesus. Ali will appear on Mount Safa’ with Moses’ rod, and Solomon’s ring to distinguish infidels from faithful. This will be when the sun will rise from the west and the door of penance shall be closed.

[Pooya/Ali Commentary 27:69] Aqa Mahdi Puya says: "Travel" in this verse implies study of the history of nations to know the consequences of their theories, policies and actions. Imam Ali said: "O my son, although I have not lived with the people gone by but I have so closely studied their deeds, the events which took place, and the traditions and vestiges they have left behind, as if I have become one of them, as if I have lived with the first and the last of them." (Nahj al Balagha)
