Sahih al-Bukhari 2486
Narrated Abu Musa:
The Prophet (ﷺ) said, "When the people of Ash`ari tribe ran short of food during the holy battles, or the 
food of their families in Medina ran short, they would collect all their remaining food in one sheet and 
then distribute it among themselves equally by measuring it with a bowl. So, these people are from 
me, and I am from them."
حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا حَمَّادُ بْنُ أُسَامَةَ، عَنْ بُرَيْدٍ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ إِنَّ الأَشْعَرِيِّينَ إِذَا أَرْمَلُوا فِي الْغَزْوِ، أَوْ قَلَّ طَعَامُ عِيَالِهِمْ بِالْمَدِينَةِ جَمَعُوا مَا كَانَ عِنْدَهُمْ فِي ثَوْبٍ وَاحِدٍ، ثُمَّ اقْتَسَمُوهُ بَيْنَهُمْ فِي إِنَاءٍ وَاحِدٍ بِالسَّوِيَّةِ، فَهُمْ مِنِّي وَأَنَا مِنْهُمْ ‏"‏‏.‏
