O you who believe! What is the matter with you, that when you are asked to march forth in the Cause of Allah (i.e. Jihad) you cling heavily to the earth? Are you pleased with the life of this world rather than the Hereafter? But little is the enjoyment of the life of this world as compared with the Hereafter. 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 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, light and heavy! Struggle in God's way with your possessions and your selves; that is better for you, did you know. 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
