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 Unless you go out (to strive), God will inflict grievous punishment on you, and bring other people in your place, and you will not be able to harm Him in the least, for God has the power over all things. 39 If ye succour him not, then surely Allah hath succoured him when these who disbelieved drave him, the second of the two, when the twain were in a cave, and when he said unto his companion: grieve not, verily Allah is with us. Then Allah sent down His calm upon him and aided him with hosts whom ye saw not, and made the word of those who disbelieved nethermost, and the word of Allah! that is the uppermost. And Allah is Mighty, Wise. 40 Go forth, whether lightly or heavily equipped, and strive and struggle, with your goods and your persons, for the cause of God. That is better for you, if you only knew. 41 Had there been [a prospect of] immediate gain, and an easy journey, they would certainly have followed thee, [O Prophet:] but the distance was too great for them. And yet, [after your return, O believers,] they will swear by God, "Had we been able to do so, we would certainly have set out with you!" - [and by thus falsely swearing] they will be destroying their own selves: for God knows indeed that they are lying! 42
