حَدَّثَنِي حَجَّاجُ بْنُ الشَّاعِرِ، حَدَّثَنَا عَبْدُ الصَّمَدِ، حَدَّثَنَا حَمَّادٌ، - يَعْنِي ابْنَ سَلَمَةَ - عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم آخَى بَيْنَ أَبِي عُبَيْدَةَ بْنِ الْجَرَّاحِ وَبَيْنَ أَبِي طَلْحَةَ ‏.‏
Translation
It was said to Anas b. Malik

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