At-Tawbah · 9:111

111. Allah, may He be glorified, has purchased from the believers their lives – despite them belonging to Him – out of His grace for a high price: Paradise. They will fight the disbelievers so that Allah’s Word is highest and they will kill the disbelievers or be killed by them. Allah has made this true promise in the Torah (the scripture of Moses), the Gospel (the scripture of Jesus), and the Qur’ān (the scripture of Muhammad (peace be upon him)). There is no one who is more faithful to his promise than Allah. so rejoice O believers, with the trade that you made with Allah, because of your gaining such a huge profit in it. That deal is the great success.
