Yahya related to me from Malik from Nafi from Ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, saw the corpse of a woman who had been slain in one of the raids, and he disapproved of it and forbade the killing of women and children.
Muwatta Malik Book 21, Hadith 9
← Previous Hadith Yahya related to me from Malik from Ibn Shihab that a son of Kab ibn Malik (Malik believed that ibn Shihab said it was Abd ar-Rahman ibn Kab) said, "The Messenger of Allah, may Allah bless him and grant him peace, forbade those who fought ibn Abi Huqayq (a treacherous jew from Madina) to kill women and children. He said that one of the men fighting had said, 'The wife of ibn Abi Huqayq began screaming and I repeatedly raised my sword against her. Then I would remember the prohibition of the Messenger of Allah, may Allah bless him and grant him peace, so I would stop. Had it not been for that, we would have been rid of her.' "

Muwatta Malik Book 21, Hadith 8 Next Hadith → Do not kill women or children or an aged, infirm person. Do not cut down fruit-bearing trees. Do not destroy an inhabited place. Do not slaughter sheep or camels except for food. Do not burn bees and do not scatter them. Do not steal from the booty, and do not be cowardly."
