Sahih al-Bukhari · Book 78: Good Manners and Form (Al-Adab) · The establishment of a bond of brotherhood and the conclusion of a treaty
Narrated `Asim:
حَدَّثَنَا مُحَمَّدُ بْنُ صَبَّاحٍ ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ زَكَرِيَّاءَ ، حَدَّثَنَا عَاصِمٌ ، قَالَ قُلْتُ لأَنَسِ بْنِ مَالِكٍ أَبَلَغَكَ أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " لاَ حِلْفَ فِي الإِسْلاَمِ ". فَقَالَ قَدْ حَالَفَ النَّبِيُّ صلى الله عليه وسلم بَيْنَ قُرَيْشٍ وَالأَنْصَارِ فِي دَارِي .
I said to Anas bin Malik, "Did it reach you that the Prophet (ﷺ) said, "There is no treaty of brotherhood in Islam'?" Anas said, "The Prophet (ﷺ) made a treaty (of brotherhood) between the Ansar and the Quraish in my home."
