Ahmad b. Harun al-Fami narrated to us. He said: Muhammad b. `Abdullah b. Ja`far b. Jami` al-Himyari narrated to us from his father from Ayyub b. Nuh from Muhammad b. Abi `Umayr from Aban al-Ahmar from Sa`d al-Kinani from al-Asbagh b. Nubata from `Abdullah b. `Abbas. He said:

The Messenger of Allah (s) said to `Ali : O `Ali! You are my vicegerent (khalifa) over my Nation in my lifetime and after my death. You are to me as Sheeth was to Adam, and as Sam was to Nuh, and as Isma`il was to Ibrahim, and as Yusha` was to Musa, and as Sham`un was to `Isa. O `Ali! you are my deputy, my inheritor, the one who will wash my body, the one who will bury me in my grave, the one who will represent my religion, and the one who will fulfill my traditions. O `Ali! You are the Commander of the Faithful, the Imam of the Muslims, the Leader of the shining believers, and the Chief of the Godfearing. O `Ali! You are the husband of the Mistress of Women, my daughter Fatima; you are the father of my two descendants al-Hasan and al-Husayn. O `Ali! Allah put the descendants of every prophet in his loins, and He put my descendants in your loins. O `Ali! Whoever loves you and aligns with you, I have loved him, and I have aligned with him, and whoever hates you and opposes you, I have hated him and opposed him; for you are from me and I am from you. O `Ali! Allah has purified us and chosen us, O `Ali! None of our ancestors from the descendants of Adam have ever committed adultery. So, none will love us except he whose birth was pure. O `Ali! Be gladdened by martyrdom, for you will be persecuted and killed after me. So, `Ali said: O Messenger of Allah! Will I be at peace with my religion? He said: You will be at peace with your religion, `Ali. Surely, you cannot be misguided, and you cannot falter. Had it not been for you, the party of Allah would not be known after me.
