O ye who believe! what is the matter with you, that, when ye are asked to go forth in the cause of Allah, 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. 38 If you do not go forth, He will punish you with a painful punishment and replace you by another nation. You will in no way harm Him; for Allah has power over all things. 39 If you do not help him, yet God has helped him already, when the unbelievers drove him forth the second of two, when the two were in the Cave, when he said to his companion, 'Sorrow not; surely God is with us.' Then God sent down on him His Shechina, and confirmed him with legions you did not see; and He made the word of the unbelievers the lowest; and God's word is the uppermost; God is All-mighty, All-wise. 40 March forth light and heavy and strive hard with your riches and your lives in the way of Allah; that is the best for you, if ye have knowledge. 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
