At the same time the Muslims are commanded to exercise self-restraint as much as possible. Force
is a dangerous weapon. It may have to be used for self-defense or self-preservation, but we must
always remember that self-restraint is pleasing in the eyes of Allah. Even when we are fighting, it
should be for a principle not out of passion.
