عَنْ مُحَمَّدِ بْنِ سَعْدِ بْنِ مَالِكٍ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ((لَا يَحِلُّ لِمُسْلِمٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلَاثٍ))
It is narrated from Sayyiduna Sa’d bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: It is not permissible for a Muslim to abandon his brother for more than three days.
