" God hath purchased of the Believers. Their persons and their goods; For their (in return) Is the Garden (of Paradise) They fight in His Cause, And slay and are slain: A promise binding on Him In Truth, through the Law, The Gospel, and the Qur’an: And who is more faithful To his Covenant than God? Then rejoice in bargain Which ye have concluded: That is the achievement supreme. "(Al- Qur'an, IX:II1)
