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 ‏"‏ ‏.‏

Abu Huraira reported Allah's Messenger (PBUH) 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. Translation Not Available
