Verily Allah hath bought of the believers their lives and their riches for the price that theirs shall be the Garden: they fight in the way of Allah and slay and are slain: a promise due thereon in the Taurat, in the Injil - and the Qur'an-and who is more faithful unto his covenant than Allah? Rejoice wherefore in your bargain which ye have made. And that it is the mighty achievement.
