Going forth into Battle

O you who believe, when you set out in the path of God, be discerning. Do not say to one who offers you peace, “You are not a believer,” driven by desire for the fleeting spoils of worldly life. With God lie abundant treasures far greater than these. You were once like them, then God graced you with His mercy. So be discerning.

4:94O ye who believe! When ye go forth (to fight) in the way of Allah, be careful to discriminate, and say not unto one who offereth you peace: "Thou art not a believer," seeking the chance profits of this life (so that ye may despoil him). With Allah are plenteous spoils. Even thus (as he now is) were ye before; but Allah hath since then been gracious unto you. Therefore take care to discriminate. Allah is ever Informed of what ye do.
