Bukhari :: Book 5 :: Volume 59 :: Hadith 652

Narrated Abu Huraira:

I have not ceased to like Banu Tamim ever since I heard of three qualities attributed to them by Allah's Apostle (He said): They, out of all my followers, will be the strongest opponent of Ad-Dajjal; 'Aisha had a slave-girl from them, and the Prophet told her to manumit her as she was from the descendants of (the Prophet) Ishmael; and, when their Zakat was brought, the Prophet said, "This is the Zakat of my people."
