Bukhari :: Book 8 :: Volume 78 :: Hadith 630

Narrated Abu Bakra:

The Prophet said, "Do you think if the tribes of Aslam, Ghifar, Muzaina and Juhaina are better than the tribes of Tamim, 'Amir bin Sa'sa'a, Ghatfan and Asad, they (the second group) are despairing and losing?" They (the Prophet's companions) said, "Yes, (they are)." He said, "By Him in Whose Hand my soul is, they (the first group) are better than them (the second group)."
