Shaykh of shias al-Mufid narrated in his “al-Amali” (Thirteenth Assembly, hadith4):

Translation:

Abu Abdillah Ja’far b. Muhammad, peace be upon him said: The Prophet, peace be upon him and his progeny, learnt that a group among the Quraish was saying: “Muhammad thinks that he has firmly connected this matter (of succession after him) with his Ahlul Bait, but when he dies, we shall snatch it away from them and place it among others.” The Prophet, peace be upon him and his progeny, came to them and addressed: “O people of Quraish, how is that you are prone to disobedience after I have gone? Do you wish to see me with a detachment of my companions hitting your faces and necks with the sword?”

Then Jibraeel, peace be upon him, descended and said: “O Muhammad! Your Sustainer sends you peaceful greetings and commands: “Say, Allah willing, and Ali b. Abi Talib.” The Prophet, peace be upon him and his progeny, said: “Allah willing, and Ali b. Abi Talib, who will attend to that among you.”
