حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ عَنْ مَالِکٍ عَنْ ابْنِ شِهَابٍ عَنْ عَطَائِ بْنِ يَزِيدَ اللَّيْثِيِّ عَنْ أَبِي أَيُّوبَ الْأَنْصَارِيِّ أَنَّ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا يَحِلُّ لِمُسْلِمٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلَاثَةِ أَيَّامٍ يَلْتَقِيَانِ فَيُعْرِضُ هَذَا وَيُعْرِضُ هَذَا وَخَيْرُهُمَا الَّذِي يَبْدَأُ بِالسَّلَامِ
سنن ابودوٗد · Hadith 4911
Abu Ayyub al-Ansari reported the Messenger of Allah ﷺ as saying: it is not allowable for a Muslim to keep apart from his brother for more than three days. When they meet, this turns away from him, and that turns away from him. The better of the two is the one who initiates in salutation.
