حَدَّثَنَا عَتَّابُ بْنُ زِيَادٍ أَخْبَرَنَا عَبْدُ اللَّهِ يَعْنِي ابْنَ مُبَارَكٍ أَنْبَأَنَا مَالِكُ بْنُ أَنَسٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَى فِي بَعْضِ مَغَازِيهِ امْرَأَةً مَقْتُولَةً فَأَنْكَرَ ذَاكَ وَنَهَى عَنْ قَتْلِ النِّسَاءِ وَالصِّبْيَانِ
