Sunan Ibn Majah, Book 24, Hadith 2948 (In-Book) ⓘ
It was narrated from Ibn ‘Umar that the Prophet saw a woman who had been killed on the road, and he forbade killing women and children.
حَدَّثَنَا يَحْيَى بْنُ حَكِيمٍ، حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ، أَنْبَأَنَا مَالِكُ بْنُ أَنَسٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم رَأَى امْرَأَةً مَقْتُولَةً فِي بَعْضِ الطَّرِيقِ فَنَهَى عَنْ قَتْلِ النِّسَاءِ وَالصِّبْيَانِ .
