Musannaf Ibn Abi Shayba 36:341

36875. Abd al-Rahim ibn Sulayman narrated to us, from Muhammad ibn Ishaq, from al-Zuhri, from Sa'id ibn al-Musayyib, from Jubayr ibn Mut'im, who said: The Messenger of Allah (may Allah bless him and grant him peace) distributed the share of the near kin (dhawi al-qurba) from Khaybar to the Banu Hashim and the Banu al-Muttalib. I and Uthman ibn Affan walked until we entered upon him, and we said: "O Messenger of Allah, these are your brothers from the Banu Hashim; their merit is not denied due to the position in which Allah has placed you among them. What do you see regarding our brothers from the Banu al-Muttalib? You have given to them while excluding us, yet we and they are in the same position regarding lineage." He said: "They have not parted from us in the Jahiliyyah nor in Islam."
