Sahih Muslim 2563 b
Abu Huraira reported Allah's Messenger (ﷺ) as saying
Don't have estranged relations (with the others) and don't nurse enmity and don't enter into a transaction when the other (has already entered) and be fellow-brothers and servants of Allah.حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي ابْنَ مُحَمَّدٍ - عَنِ الْعَلاَءِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ تَهَجَّرُوا وَلاَ تَدَابَرُوا وَلاَ تَحَسَّسُوا وَلاَ يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا " .
