Do Not Hate One Another

 حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ تَبَاغَضُوا، وَلاَ تَحَاسَدُوا، وَلاَ تَدَابَرُوا، وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا، وَلاَ يَحِلُّ لِمُسْلِمٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلاَثِ لَيَالٍ ‏"‌‏. 

Narrated Anas bin Malik: 

Allah's Messenger (ﷺ) said, "Do not hate one another, nor be jealous of one another; and do not desert one another, but O Allah's worshipers! Be Brothers! And it is unlawful for a Muslim to desert his brother Muslim (and not to talk to him) for more than three nights."
