Bukhari :: Book 4 :: Volume 56 :: Hadith 802
Narrated Said Al-Umawi:
I was with Marwan and Abu Huraira and heard Abu Huraira saying, "I heard the trustworthy, truly inspired one (i.e. the Prophet ) saying, 'The destruction of my followers will be brought about by the hands of some youngsters from Quraish." Marwan asked, "Youngsters?" Abu Huraira said, "If you wish, I would name them: They are the children of so-and-so and the children of so-and-so."
