حَدَّثَنَا يُونُسُ بْنُ عَبْدِ الأَعْلَى، حَدَّثَنَا أَيُّوبُ بْنُ سُوَيْدٍ، عَنْ يُونُسَ بْنِ يَزِيدَ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّ جُبَيْرَ بْنَ مُطْعِمٍ، أَخْبَرَهُ أَنَّهُ، جَاءَ هُوَ وَعُثْمَانُ بْنُ عَفَّانَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم يُكَلِّمَانِهِ فِيمَا قَسَمَ مِنْ خُمُسِ خَيْبَرَ لِبَنِي هَاشِمٍ وَبَنِي الْمُطَّلِبِ فَقَالاَ قَسَمْتَ لإِخْوَانِنَا بَنِي هَاشِمٍ وَبَنِي الْمُطَّلِبِ وَقَرَابَتُنَا وَاحِدَةٌ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنَّمَا أَرَى بَنِي هَاشِمٍ وَبَنِي الْمُطَّلِبِ شَيْئًا وَاحِدًا ‏"‏ ‏.‏

It wasnarrated from Sa’eed bin Musayyab that Jubair bin Mut’im toldhimthat he and ‘Uthman bin ‘Affan came to the Messenger of Allah(PBUH) to speak to him about the way in which the one fifth fromKhaibar had been distributed to Banu Hashim and Banu Muttalib. Theysaid: “You have distributed it to our brothers Banu Hashim and BanuMuttalib, but we are related to you (to Banu Hashim) in the same way(as Banu Muttalib).” The Messenger of Allah (PBUH) said: “Rather Ithink that Banu Hashim and Banu Muttalib are the same.”* Translation Not Available
