(6) باب ذِكْرِ أَسْلَمَ وَغِفَارَ وَمُزَيْنَةَ وَجُهَيْنَةَ وَأَشْجَعَ.
Narrated Abu Bakra:
Al-Aqra' bin Habis said to the Prophet (ﷺ) "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 (ﷺ) 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).
