Ibn al-Musayyab told us; A son of Sa"d bin Abi Waqqas narrated (a hadeeth) from his father, so I entered upon Sa"d and said: I was told something from you, about when the Messenger of Allah (ﷺ) left ‘Ali in charge of Madinah. He got angry and said: who told you that? I did not want to tell him that his son had told it to me, lest he get angry with him. Then he said:

When the Messenger of Allah (ﷺ) set out on the campaign of Tabook, he appointed "Ali in charge of Madinah and "Ali said: O Messenger of Allah. I do not like you to go anywhere but I am with you. He said: "Does it not please you to be to me as Haroon was to Moosa? Except that there will be no Prophet (ﷺ) after me.”
