Sahih Bukhari Volume 5, Book 59, Hadith Number 538.

Narrated By Jubair bin Mutim : Uthman bin ‘Affan and I went to the Prophet and said, “You had given Banu Al-Muttalib from the Khumus of Khaibar’s booty and left us in spite of the fact that we and Banu Al-Muttalib are similarly related to you.” The Prophet said, “Banu Hashim and Banu Al-Muttalib only are one and the same.” So the Prophet did not give anything to Banu Abd Shams and Banu Nawfal.
