مسلم:٢٤٥٥حَدَّثَنَا حَسَنٌ الْحُلْوَانِيُّ حَدَّثَنَا عَمْرُو بْنُ عَاصِمٍ حَدَّثَنَا هَمَّامٌ عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ عَنْ أَنَسٍ قَالَ

كَانَ النَّبِيُّ ﷺ لاَ يَدْخُلُ عَلَى أَحَدٍ مِنَ النِّسَاءِ إِلاَّ عَلَى أَزْوَاجِهِ إِلاَّ أُمِّ سُلَيْمٍ فَإِنَّهُ كَانَ يَدْخُلُ عَلَيْهَا فَقِيلَ لَهُ فِي ذَلِكَ فَقَالَ إِنِّي أَرْحَمُهَا قُتِلَ أَخُوهَا مَعِي
