O believers, what is amiss with you, that when it is said to you, 'Go forth in the way of God,' you sink down heavily to the ground? Are you so content with this present life, rather than the world to come? Yet the enjoyment of this present life, compared with the world to come, is a little thing. 38 If ye march not forth, He will torment you with a torment afflictive, and will substitute for you a people - other than you; and Him ye cannot hurt in aught; and Allah is over everything Potent. 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 Whether lightly or heavily, march on and fight for the Way of Allah, with your wealth and your persons. This will be best for you, if you but knew. 41 Had the gain been immediate and the journey shorter, they would have followed you: but the distance seemed too great for them. Yet they will swear by God, "Had we been able, we would have gone out with you." They bring ruin upon themselves. God knows that they are surely lying. 42
