Arabic hadith text
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 ". فَقَالَقَدْ حَالَفَ النَّبِيُّ صلى الله عليه وسلم بَيْنَ قُرَيْشٍ وَالأَنْصَارِ فِي دَارِي
Translation
Narrated `Asim
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."
