1131 - Al-Hasan narrated to us, who said: Abu Abdullah al-Husayn ibn Rashid al-Tafawi and al-Sabah ibn Abdullah Abu Bashar, a neighbor of Balad ibn al-Muhbir, both narrated similarly in wording, with one adding to the other. They both said: Qays ibn al-Rabi narrated to us, who said: Sa'd al-Khuffaf narrated to me from Atiyyah, from Mahdhuq ibn Zayd, that the Messenger of Allah (peace be upon him and his holy progeny) established brotherhood among the Muslims
and then said: O Ali, you are my brother, and you are to me in status like Harun to Musa, except that there is no prophet after me .... Then a caller will call from beneath the Throne: Yes, a fine father is your father Ibrahim
and a fine brother is your brother Ali. Rejoice, O Ali, you will be clothed when you are clothed, called when you are called, and live when you are alive.
