But (do not kill) those who have allied with a people between you and whom there is a (peace) treaty, or who (losing heart) come to you in such a state that their breasts are afflicted (with this obsession) whether they should fight you or their own people. If Allah had so willed, He (strengthening their hearts) would have given them supremacy over you. Then they would certainly have fought you. So if they keep away from you and do not fight you and send you (a message) for peace, then (in the interest of peace) Allah has left no way open for you (to launch any aggression) against them.
