حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَهْبٌ، حَدَّثَنَا شُعْبَةُ، عَنْ مُحَمَّدِ بْنِ أَبِي يَعْقُوبَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكْرَةَ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " أَرَأَيْتُمْ إِنْ كَانَ أَسْلَمُ وَغِفَارُ وَمُزَيْنَةُ وَجُهَيْنَةُ خَيْرًا مِنْ تَمِيمٍ وَعَامِرِ بْنِ صَعْصَعَةَ وَغَطَفَانَ وَأَسَدٍ، خَابُوا وَخَسِرُوا ". قَالُوا نَعَمْ. فَقَالَ " وَالَّذِي نَفْسِي بِيَدِهِ إِنَّهُمْ خَيْرٌ مِنْهُمْ ".
