Prophet, make war on the unbelievers and the hypocrites and deal rigorously with them. Hell shall be their home: An evil fate.
(Koran 9:73

Believers, make war on the infidels who dwell around you. Deal firmly with them. Know that God is with the righteous.
(Koran 9:123)

The believers who stay at home- apart from those that suffer from a grave impediment- are not the equal of those who fight with their goods and their persons. God has given them a higher rank than those who stay at home. God has promised all a good reward; but far richer is the recompense of those who fight for Him...He that leaves his dwelling to fight for God and His apostle and is then overtaken by death, shall be rewarded by God...The unbelievers are your inveterate enemies.
(Koran 4:95-101)

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 "trifling are the pleasures of this life. The hereafter is better for those who would keep from evil..."
(Koran 4:74-78)
