Let those fight in the cause of God Who sell the life of this world for the hereafter. To him who fighteth in the cause of God,- whether he is slain or gets victory - Soon shall We give him a reward of great (value). (4:74)

Hast thou not turned Thy vision to those who were told to hold back their hands (from fight) but establish regular prayers and spend in regular charity? When (at length) the order for fighting was issued to them, behold! a section of them feared men as - or even more than - they should have feared God: They said: "Our Lord! Why hast Thou ordered us to fight? Wouldst Thou not Grant us respite to our (natural) term, near (enough)?" Say: "Short is the enjoyment of this world: the Hereafter is the best for those who do right: Never will ye be dealt with unjustly in the very least! (4:77)

Then fight in God's cause - Thou art held responsible only for thyself - and rouse the believers. It may be that God will restrain the fury of the Unbelievers; for God is the strongest in might and in punishment. (4:84)

O ye who believe! what is the matter with you, that, when ye are asked to go forth in the cause of God, ye cling heavily to the earth? Do ye prefer the life of this world to the Hereafter? But little is the comfort of this life, as compared with the Hereafter. (9:38)

Unless ye go forth, He will punish you with a grievous penalty, and put others in your place; but Him ye would not harm in the least. For God hath power over all things. (9:39)

Go ye forth, (whether equipped) lightly or heavily, and strive and struggle, with your goods and your persons, in the cause of God. That is best for you, if ye (but) knew. (9:41)
