Sunan Ibn Majah, Volume 4, Book 24, Hadith 2881 (DarusSalam) ⓘ

It was narrated from Sa’eed bin Musayyab that Jubair bin Mut’im told him that he and ‘Uthman bin ‘Affan came to the Messenger of Allah to speak to him about the way in which the one fifth from Khaibar had been distributed to Banu Hashim and Banu Muttalib. They said: “You have distributed it to our brothers Banu Hashim and Banu Muttalib, but we are related to you (to Banu Hashim) in the same way (as Banu Muttalib).” The Messenger of Allah said: “Rather I think that Banu Hashim and Banu Muttalib are the same.”*

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 ‏" ‏ ‏.‏
