47:4When you encounter those who disbelieve, strike at their necks. Then, when you have routed them, bind them firmly. Then, either release them by grace, or by ransom, until war lays down its burdens. Had God willed, He could have defeated them Himself, but He thus tests some of you by means of others. As for those who are killed in the way of God, He will not let their deeds go to waste.

47:8But as for those who disbelieve, for them is perdition, and He will waste their deeds.

47:33O you who believe! obey God, and obey the Messenger, and do not let your deeds go to waste.

47:35So do not waver and call for peace while you have the upper hand. God is with you, and He will not waste your efforts.
