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."  

أَنَّ النَّبِيَّ ﷺ قَالَ لاَ حِلْفَ فِي الإِسْلاَمِ فَقَالَ قَدْ حَالَفَ النَّبِيُّ ﷺ بَيْنَ قُرَيْشٍ وَالأَنْصَارِ فِي دَارِي  

The Prophet ﷺ brought the Ansar and the Quarish people into alliance in my house at Medina, and he invoked Allah for one month against the tribe of Bani Sulaim in (the last rakʿa of each compulsory) prayer.  

حَالَفَ النَّبِيُّ ﷺ بَيْنَ الأَنْصَارِ وَقُرَيْشٍ فِي دَارِي الَّتِي بِالْمَدِينَةِ وَقَنَتَ شَهْرًا يَدْعُو عَلَى أَحْيَاءٍ مِنْ بَنِي سُلَيْمٍ  

You must have heard this that Messenger of Allah ﷺ said: There is no alliance (hilf) of brotherhood in Islam. Anas said: Messenger of Allah ﷺ established the bond of fraternity between the Quraish and the Ansar in his home.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ حِلْفَ فِي الإِسْلاَمِ فَقَالَ أَنَسٌ قَدْ حَالَفَ رَسُولُ اللَّهِ ﷺ بَيْنَ قُرَيْشٍ وَالأَنْصَارِ فِي دَارِهِ  

Anas reported Messenger of Allah ﷺ established fraternity between the Quraish and the Ansar in his house at Medina. (Using translation from Muslim 2529b)   

عَنْ رَسُولِ اللَّهِ ﷺ «أَنَّهُ حَالَفَ بَيْنَ قُرَيْشٍ وَالْأَنْصَارِ فِي دُورِهِمْ بِالْمَدِينَةِ»
