O Ye who believe! what aileth you that when it is said unto you: march forth in the way of Allah, ye are weighed down earthward? Are ye pleased with the life of the world rather than the Hereafter? whereas the enjoyment of the life of the world by the side of the Hereafter is but little. 38 If you do not go forth, He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all. And Allah is over all things competent. 39 If ye help not (your leader), (it is no matter): for Allah did indeed help him, when the Unbelievers drove him out: he had no more than one companion; they two were in the cave, and he said to his companion, "Have no fear, for Allah is with us": then Allah sent down His peace upon him, and strengthened him with forces which ye saw not, and humbled to the depths the word of the Unbelievers. But the word of Allah is exalted to the heights: for Allah is Exalted in might, Wise. 40 Go forth to war, whether it be easy or difficult [for you,] and strive hard in God's cause with your possessions and your lives: this is for your own good - if you but knew it! 41 Were it a gain near at hand, and an easy journey, they would have followed thee; but the distance was too far for them. Still they will swear by God, 'Had we been able, we would have gone out with you,' so destroying their souls; and God knows that they are truly liars. 42
