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.

47:30Had We willed, We could have shown them to you, and you would have recognized them by their marks. Yet you will recognize them by their tone of speech. And God knows your actions.
