Narrated Jubair bin Mut'im:

'Uthman bin Affan went (to the Prophet) and said, "O Allah's Apostle! You gave property to Bani Al-Muttalib and did not give us, although we and they are of the same degree of relationship to you." The Prophet ﷺ said, "Only Bani Hashim and Bani Al Muttalib are one thing (as regards family status)." Narrated Urwa bin Az-Zubair: 'Abdullah bin Az-Zubair went with some women of the tribe of Bani Zuhra to 'Aisha who used to treat them nicely because of their relation to Allah's Apostle.

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 ﷺ " إِنَّمَا بَنُو هَاشِمٍ وَبَنُو الْمُطَّلِبِ شَىْءٌ وَاحِدٌ ".
