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.' "
