Muhammad - 47:4
When you meet those who disbelieve in battle, strike their centers of control. And when you are victorious, take them captive and release them either for nothing or for ransom. Do this until the state of war ceases. Had Allah willed, He would have spared you the trouble of war, but He is testing you one against another in this way. As for those who are slain in the way of Allah, He will not make their deeds vain.
