BEHOLD, God has bought of the believers their lives and their possessions, promising them paradise in return,[and so] they fight in God's cause, and slay, and are slain: a promise which in truth He has willed upon Himself in [the words of] the Torah, and the Gospel, and the Qur'an. And who could be more faithful to his covenant than God? Rejoice, then, in the bargain which you have made with Him: for this, this is the triumph supreme!
