Abu Huraira reported Allah's Messenger (ﷺ) as saying:
وَحَدَّثَنِي أَحْمَدُ بْنُ سَعِيدٍ الدَّارِمِيُّ ، حَدَّثَنَا حَبَّانُ ، حَدَّثَنَا وُهَيْبٌ ، حَدَّثَنَا سُهَيْلٌ ، عَنْ أَبِيهِ ، عَنْ أَبِي هُرَيْرَةَ ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ تَبَاغَضُوا وَلاَ تَدَابَرُوا وَلاَ تَنَافَسُوا وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا " .
Don't bear aversion against one another and don't be jealous of one another and be servants of Allah.
