It was
narrated that Safwan bin ‘Assil said:
“The Messenger of Allah
(ﷺ) sent us in a military detachment and said: ‘Go in the Name of
Allah, and in the cause of Allah. Fight those who disbelieve in
Allah.
Do not mutilate, do not be treacherous, do not steal from the
spoils
of war, and do not kill children.’”
