حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، عَنِ ابْنِ الْمُسَيَّبِ، عَنْ جُبَيْرِ بْنِ مُطْعِمٍ، قَالَ مَشَيْتُ أَنَا وَعُثْمَانُ بْنُ عَفَّانَ،، فَقَالَ يَا رَسُولَ اللَّهِ أَعْطَيْتَ بَنِي الْمُطَّلِبِ وَتَرَكْتَنَا، وَإِنَّمَا نَحْنُ وَهُمْ مِنْكَ بِمَنْزِلَةٍ وَاحِدَةٍ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ إِنَّمَا بَنُو هَاشِمٍ وَبَنُو الْمُطَّلِبِ شَىْءٌ وَاحِدٌ ‏" ‏‏.‏

وَقَالَ اللَّيْثُ حَدَّثَنِي أَبُو الأَسْوَدِ، مُحَمَّدٌ عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، قَالَ ذَهَبَ عَبْدُ اللَّهِ بْنُ الزُّبَيْرِ مَعَ أُنَاسٍ مِنْ بَنِي زُهْرَةَ إِلَى عَائِشَةَ، وَكَانَتْ أَرَقَّ شَىْءٍ لِقَرَابَتِهِمْ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم‏.‏
