O you who believe! What (excuse) have you that when it is said to you: Go forth in Allah's way, you should incline heavily to earth; are you contented with this world's life instead of the hereafter? But the provision of this world's life compared with the hereafter is but little. 38 If you do not march for His cause, He will afflict your with a painful punishment and replace you by another nation and your (destruction) will not harm Him at all. God has power over all things. 39 If you do not help him (Prophet Mohammed – peace and blessings be upon him), Allah has helped him – when he had to go forth due to the mischief of the disbelievers, just as two men* – when they were in the cave, when he was saying to his companion “Do not grieve; indeed Allah is with us”; then Allah caused His calm to descend upon him and helped him with armies you did not see, and disgraced the word of the disbelievers; and Allah’s Word is supreme; and Allah is the Almighty, the Wise. (* The Holy Prophet migrated only with S. Abu Bakr (who later became the first caliph) as his sole companion.) 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 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
