‘Umr ibn ‘Abd Al-‘Aziz wrote to one of his governors: We have been made aware that the Messenger of Allah (SAW), whenever He sent out a detachment, said to them: “Attack in the name of Allah and for the sake of Allah, fighting whoever disbelieves in Allah; do not steal from the spoils, do not deceive, do not mutilate, and do not kill children; tell this to your armies and your detachments, Allah willing, and peace be upon you.”
