Yahya ibn Yahya al-Tamimi, Abu Ja'far Muhammad ibn al-Sabbah, Ubaydullah al-Qawariri, and Surayj ibn Yunus narrated to us—all of them from Yusuf al-Majishun, and the wording is that of Ibn al-Sabbah—Yusuf Abu Salamah al-Majishun narrated to us, Muhammad ibn al-Munkadir narrated to us, from Sa'id ibn al-Musayyab, from Amir ibn Sa'd ibn Abi Waqqas, from his father, who said: The Messenger of Allah, peace and blessings be upon him, said to Ali: "You are to me in the position of Harun to Musa, except that there is no prophet after me." Sa'id said: I wished to hear this directly from Sa'd's own mouth, so I met Sa'd and told him what Amir had narrated to me. He said: I heard it myself. I said: You heard it yourself? He placed his two fingers on his ears and said: Yes, and if not, may they become deaf.
