عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ ((لَا تَبَاغَضُوا وَلَا تَحَاسَدُوا وَلَا تَدَابَرُوا وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا وَلَا يَحِلُّ لِمُسْلِمٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلَاثِ لَيَالٍ يَلْتَقِيَانِ فَيَصُدُّ هَذَا وَيَصُدُّ هَذَا وَخَيْرُهُمَا الَّذِي يَبْدَأُ بِالسَّلَامِ))
Narrated by Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Do not harbor malice and envy against one another, avoid mutual estrangement and enmity, O servants of Allah! Become brothers to one another. It is not permissible for any Muslim to abandon his brother for more than three days; when the two meet, this one turns away and that one turns away, and the better of the two is the one who initiates the greeting of peace.
