Narrated Abu Bakra:Al-Aqra' bin H`Abis 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).Abu Huraira said, "(The Prophet said), '(The people of) Bani Aslam, Ghifar and some people of Muzaina (or some people of Juhaina or Muzaina) are better in Allah's Sight (or on the Day of Resurrection) than the tribes of Asad, Tamim, Hawazin and Ghatafan.'
