Al-Husayn b. Ahmad b. Idris narrated to us. He said: My father narrated to us from Muhammad b. al-Husayn b. Abi’l Khattab and Ya`qub b. Yazid and Muhammad b. Abi’l Suhban altogether from Muhammad b. Abi `Umayr from Aban b. `Uthman from al-Sadiq Ja`far b. Muhammad from his father from his grandfather . He said:

A Bedouin came to the Messenger of Allah (s), so he came out to him in a cloak dyed in a reddish musk. So, he said: O Muhammad! You have come out to me as though you are a young man! So, he (s) said: Yes, Bedouin. I am a young man, son of a young man, brother of a young man. So, he said: O Muhammad! As for being a young man, then yes; but how are you the son of a young man and brother of a young man? So, he (s) said: Have you not heard the saying of Allah, “They said: we heard a young man named Ibrahim mentioned them” (21:60)? Surely, I am the son of Ibrahim. As for the brother of a young man: on the day of Uhud, a caller called from heaven: “There is no sword except dhulfiqar and there is no young man except `Ali.” `Ali is my brother, and I am his brother.
