Allah’s War Against the Unbelievers

9:111 Allah has bought from the believers their lives and their wealth in return for Paradise; they fight in the Way of Allah, kill and get killed. That is a true promise from Him in the Torah, the Gospel and the Qur’an; and who fulfills his promise better than Allah? Rejoice then at the bargain you have made with Him; for that is the great triumph.

61:9 It is He Who sent His Messenger forth with the guidance and the religion of truth, to make it triumph over every religion, even though the idolaters may be averse.
