Jubayr bin Mut'im and Uthman bin Affan (may Allah be pleased with them both) came to speak to the Messenger of Allah (peace and blessings be upon him) about what he (peace and blessings be upon him) had given from the one-fifth to Banu Hashim and Banu al-Muttalib. I said: O Messenger of Allah! You have given a share to our brothers from Banu al-Muttalib and left us out, although our kin and their kin are the same. The Prophet (peace and blessings be upon him) said: "Banu Hashim and Banu al-Muttalib are one and the same." Jubayr said: He (peace and blessings be upon him) gave nothing from the one-fifth to Banu Abd Shams and Banu Nawfal, as he had given to Banu Hashim and Banu al-Muttalib. And Abu Bakr (may Allah be pleased with him) also used to distribute the one-fifth like the Messenger of Allah (peace and blessings be upon him), except that he did not give to the relatives of the Messenger of Allah (peace and blessings be upon him) what the Prophet (peace and blessings be upon him) used to give them from the one-fifth; and Umar and Uthman (may Allah be pleased with them both) used to give it.
