Let those who would exchange the life of this world for the hereafter, fight for the cause of God; whoever fights for the cause of God, whether he dies or triumphs, We shall richly reward him…. The true believers fight for the cause of God, but the infidels fight for the devil. Fight then against the friends of Satan…. Say: “Tri-fling are the pleasures of this life. The hereafter is better for those who would keep from evil….” (Koran 4:74–78)
