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 go forth, He will punish you with a painful punishment and replace you by another nation. You will in no way harm Him; for Allah 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, whether you are light (being healthy, young and wealthy) or heavy (being ill, old and poor), strive hard with your wealth and your lives in the Cause of Allah. This is better for you, if you but knew. 41 Had it been an easy gain and a moderate trip, the hypocrites would have followed you, but distant to them was the journey. And they will swear by Allah, "If we were able, we would have gone forth with you," destroying themselves [through false oaths], and Allah knows that indeed they are liars. 42
