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.

47:18Are they just waiting until the Hour comes to them suddenly? Its tokens have already come. But how will they be reminded when it has come to them?

47:31We will certainly test you, until We know those among you who strive, and those who are steadfast, and We will test your reactions.
