Jihad
Bulugh al-Maram 1286
Ibn 'Umar (RAA) narrated that The Messenger of Allah (ﷺ) saw a woman who was killed in one of his expeditions, so he disapproved the killing of women and children. Agreed upon.
وَعَنْ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا; { أَنَّ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-رَأَى اِمْرَأَةً مَقْتُولَةً فِي بَعْضِ مَغَازِيهِ, فَأَنْكَرَ قَتْلَ اَلنِّسَاءِ وَالصِّبْيَانِ } مُتَّفَقٌ عَلَيْهِ 1‏ .‏
