O YOU who have attained to faith! What is amiss with you that, when you are called upon, "Go forth to war in God's cause," you cling heavily to the earth? Would you content yourselves with [the comforts of] this worldly life in preference to [the good of] the life to come? But the enjoyment of life in this world is but a paltry thing when compared with the life to come! 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 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 the gain been immediate or the journey easy, they would have followed you; but the distance seemed far to them. Yet they will swear by Allah: 'Had we been able, we would have gone out with you' They bring destruction upon their souls. Allah knows that they are lying. 42
