Bukhari

Narrated Abu Bakra: Al-Aqra' bin Habis said to the Prophet "Nobody gave you the pledge of allegiance but the robbers of the pilgrims (i.e. those who used to rob the pilgrims) from the tribes of Aslam, Ghifar, Muzaina." (Ibn Abi Ya'qub is in doubt whether Al-Aqra' added. 'And Juhaina.') The Prophet said, "Don't you think that the tribes of Aslam, Ghifar, Muzaina (and also perhaps) Juhaina are better than the tribes of Bani Tamim, Bani Amir, Asad, and Ghatafan?" Somebody said, "They were unsuccessful and losers!" The Prophet said, "Yes, by Him in Whose Hands my life is, they (i.e. the former) are better than they (i.e. the latter).

Sulaiman bin Harb narrated to us, he said: Hammad narrated to us, from Ayyub, from Muhammad, and from Abu Hurairah (may Allah be pleased with him) who narrated that the Prophet Muhammad (peace and blessings be upon him) said: Some people from the tribes of Aslam, Ghifar, Muzaina, and Juhaina—or he said: some people from Muzaina, or he said: some people from Juhaina—will be, in the sight of Allah, or he said: on the Day of Resurrection, better than the tribes of Asad, Tamim, Hawazin, and Ghatafan.
