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 you do not march forth, Allah will chastise you grievously and will replace you by another people, while you will in no way be able to harm Him. Allah has power over everything. 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 Go ye forth, (whether equipped) lightly or heavily, and strive and struggle, with your goods and your persons, in the cause of Allah. That is best for you, if ye (but) knew. 41 Had the gain been immediate and the journey shorter, they would have followed you: but the distance seemed too great for them. Yet they will swear by God, "Had we been able, we would have gone out with you." They bring ruin upon themselves. God knows that they are surely lying. 42
