حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، عَنْ حُمَيْدٍ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ قَدِمَ عَلَيْنَا عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ فَآخَى رَسُولُ اللَّهِ صلى الله عليه وسلم بَيْنَهُ وَبَيْنَ سَعْدِ بْنِ الرَّبِيعِ‏.‏

Narrated Anas: `Abdur-Rahman bin `Auf came to us and Allah's Messenger (ﷺ) established a bond of brotherhood between him and Sa`d bin Rabi`a.

Sahih al-Bukhari · Book 39 · Hadith 2294

حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ زَكَرِيَّاءَ، حَدَّثَنَا عَاصِمٌ، قَالَ قُلْتُ لأَنَسٍ رضى الله عنه 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.‏

Narrated `Asim: I heard Anas bin Malik, "Have you ever heard that the Prophet (ﷺ) said, 'There is no alliance in Islam?' " He replied, "The Prophet (ﷺ) made alliance between Quraish and the Ansar in my house."
