It is narrated from Musa Jahni, he says: I went to Fatimah bint Ali, my companion Abu Sahl asked her: How old are you? She said: Eighty-six years. Abu Sahl asked: What have you heard about your father (Sayyiduna Ali, may Allah be pleased with him)? She said: Sayyidah Asma bint Umais, may Allah be pleased with her, narrated that the Messenger of Allah, peace and blessings be upon him, said to Sayyiduna Ali, may Allah be pleased with him: "Your position to me is like that of Harun (Aaron) to Musa (Moses), except that there is no prophet after me."
