It is narrated from Jubayr bin Mut'im and Uthman bin Affan (may Allah be pleased with them both) that: I and Uthman bin Affan went to the Messenger of Allah (peace and blessings be upon him), and we said: "O Messenger of Allah! You have given to Banu al-Muttalib and left us out, while we and they are alike." The Messenger of Allah (peace and blessings be upon him) said: "Banu al-Muttalib and Banu Hashim are one and the same."
