Do not hate each other; do not envy each other; do not desert each other; and be the servants of Allah as brethren. It is not allowed for a Muslim to keep apart from his brother for more than three days. (Using translation from Abū Dāʾūd 4910)

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَا تَبَاغَضُوا وَلَا تَحَاسَدُوا وَلَا تَدَابَرُوا وَكُونُوا عِبَادًا لِلَّهِ إِخْوَانًا وَلَا يَحِلُّ لِمُسْلِمٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلَاثٍ»
