Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) narrates: When the Messenger of Allah (peace and blessings be upon him) allotted the share of the near relatives to Banu Hashim and Banu al-Muttalib, Sayyiduna Uthman bin Affan (may Allah be pleased with him) and I came to him and said: O Messenger of Allah, these are Banu Hashim; their excellence is not denied, because of the position Allah has given you among them. But do you see that you gave our brothers, Banu al-Muttalib, and deprived us, while we and they stand at the same level in relation to you? He (peace and blessings be upon him) said: "They did not separate from me, neither in the Jahiliyyah nor in Islam; Banu Hashim and Banu al-Muttalib are one and the same thing," and he (peace and blessings be upon him) interlaced his fingers.
