It is narrated from Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) that Sayyiduna Uthman bin Affan (may Allah be pleased with him) asked the Prophet (peace and blessings be upon him), when he (peace and blessings be upon him) gave Banu Hashim and Banu al-Muttalib from the khumus of Khaybar and did not give Banu Abd Shams and Banu Abd Manaf, and he (peace and blessings be upon him) said: "Banu Hashim and Banu al-Muttalib are one and the same thing."
