“One day I went to see Ali ibn al-Husayn (a.s.).” He said, “O Hakam do you know the verse (of the Holy Quran) from which Ali ibn abu Talib had learned who his assassin was and the extremely great matters of which he would speak to people? “ Al-Hakam has said that I said to myself in my mind, “ I have now a chance to learn of the knowledge of Ali ibn al-Husayn (a.s.) with which I will learn of those extremely great matters.” The narrator has said that he replied the Imam (a.s.), “No, O son of the Messenger of Allah, I do not know.” He has said that he then said, “Please tell me, O son of the Messenger of Allah, which verse is it?” the Imam (a.s.) said, “It, I swear by Allah, is the words of Allah, Majestic is Whose mention, “We have not sent any messenger or prophet before you (or a Muhahhdath) one who hears from the angels. (22:52) Ali ibn abu Talib (a.s.) was a Muhaddath. At this point a man called ‘Abdallah ibn Zayd who was a brother of Ali from his mother’s side said, “Glory belongs to Allah. A Muhaddath1!” It seemed as if he did not believe it. Abu Ja‘far (a.s.) then turned to us and said, “Do not have any doubts, I swear by Allah, that the son of your mother after all did have knowledge of this fact.” The narrator has said that when the Imam (a.s.) said so the man kept silent. The Imam (a.s.) then said, “This is the issue in which abu al-Khattab perished. He never learned what was the explanation of the prophet and a Muhaddath.”
