Abī `Umair, from someone he mentioned, from Abū `Abd-Allah, peace be on him, who said: “The Qā’im will not reappear until the deposits of Allah, Mighty and Majestic be He, are brought forth. When these are brought forth, he will reappear and will fight against the enemies of Allah and kill them.”
667. Kamāl al-dīn2: Al-Muẓaffar b. Ja`far al-Muẓaffar, may Allah be satisfied with him, from Ja`far b. Muḥammad b. Mas`ūd, from his father, from `Alī b. Muḥammad, from Aḥmad b. Muḥammad, from al-Ḥasan b. Maḥbūb, from Ibrāhīm al-Karkhī who said:
I—or someone—asked (Imam) Abū `Abd-Allah, peace be on him, “May Allah set right your affairs! Wasn’t `Alī, peace be on him, strong in the religion of Allah, Mighty and Majestic be He?” He replied, “Yes [he was].” I said, “Then how did the people defeat him and why didn’t he repel them? What stopped him from doing so?” He answered, “A verse from the Book of Allah, Mighty and Majestic be He, prevented him from doing so.” I said, “And what was that verse?”
He replied, “The saying of Allah, Mighty and Majestic be He, ‘Had they been separated, We would have surely punished those who disbelieved from amongst them with a painful punishment.’3 Allah, Mighty and Majestic be He, put in the loins of the disbelievers and hypocrites the deposits of the believers. `Alī, peace be on him, did not kill the fathers until the deposits came out [i.e. their faithful children were born]. When the deposits came out, he stood up against [the opponents] and fought against them. The same applies to the Qā’im from our Ahl al-Bait. He will not reappear until the deposits of Allah, Mighty and Majestic be He, appear. When they all appear, he will stand up against [his opponents] and will kill them.”
