Sa'id bin al-Musayyib (may Allah have mercy on him) says that Jubayr bin Mut'im (may Allah be pleased with him) informed him: Uthman bin Affan and I (may Allah be pleased with them both) came to the Messenger of Allah (peace and blessings be upon him). We were speaking with him (peace and blessings be upon him), and he (peace and blessings be upon him) had distributed the spoils of Khaybar between Banu Hashim and Banu al-Muttalib. We said: O Messenger of Allah, you have distributed the spoils among our brothers, Banu al-Muttalib bin Abd Manaf, while you have given us nothing, though our kinship is the same as their kinship. The Messenger of Allah (peace and blessings be upon him) said to us: "Banu Hashim and Banu al-Muttalib are one and the same thing." Jubayr bin Mut'im (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) did not distribute anything from the khumus to Banu Abd Shams and Banu Nawfal as he distributed to Banu Hashim and Banu al-Muttalib.
