أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، قَالَ أَنْبَأَنَا مُحَمَّدُ بْنُ إِسْحَاقَ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ جُبَيْرِ بْنِ مُطْعِمٍ، قَالَ لَمَّا قَسَمَ رَسُولُ اللَّهِ صلى الله عليه وسلم سَهْمَ ذِي الْقُرْبَى بَيْنَ بَنِي هَاشِمٍ وَبَنِي الْمُطَّلِبِ أَتَيْتُهُ أَنَا وَعُثْمَانُ بْنُ عَفَّانَ فَقُلْنَا يَا رَسُولَ اللَّهِ هَؤُلاَءِ بَنُو هَاشِمٍ لاَ نُنْكِرُ فَضْلَهُمْ لِمَكَانِكَ الَّذِي جَعَلَكَ اللَّهُ بِهِ مِنْهُمْ أَرَأَيْتَ بَنِي الْمُطَّلِبِ أَعْطَيْتَهُمْ وَمَنَعْتَنَا فَإِنَّمَا نَحْنُ وَهُمْ مِنْكَ بِمَنْزِلَةٍ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنَّهُمْ لَمْ يُفَارِقُونِي فِي جَاهِلِيَّةٍ وَلاَ إِسْلاَمٍ إِنَّمَا بَنُو هَاشِمٍ وَبَنُو الْمُطَّلِبِ شَىْءٌ وَاحِدٌ ‏"‏ ‏.‏ وَشَبَّكَ بَيْنَ أَصَابِعِهِ ‏.‏

It was narrated that Jubair bin Mut'im said: "When the Messenger of Allah distributed the share for his relatives to Banu Hashim and BanuA-Muttalib, I came to himwith 'Uthman bin 'Affan and we said: 'O Messenger of Allah, no one denies the virtue of Banu Hashim because of the relationship between you and them. But how come you have given (a share) to Banu Al-Muttalib and not to us? They and we share the same degree of relationship to you. 'The Messenger of Allah said: "They did not abandon me during the Jahiliyyah or in Islam. Banu Hashim and Banu Al-Muttalib are the same thing, and he interlaced his fingers."
