O Ye who believe! what aileth you that when it is said unto you: march forth in the way of Allah, ye are weighed down earthward? Are ye pleased with the life of the world rather than the Hereafter? whereas the enjoyment of the life of the world by the side of 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 aid the Prophet - Allah has already aided him when those who disbelieved had driven him out [of Makkah] as one of two, when they were in the cave and he said to his companion, "Do not grieve; indeed Allah is with us." And Allah sent down his tranquillity upon him and supported him with angels you did not see and made the word of those who disbelieved the lowest, while the word of Allah - that is the highest. And Allah is Exalted in Might and Wise. 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 Were there a gear nigh and a journey moderate, they would have surely followed thee, but the distance seemed far unto them. And anon they will be swearing by Allah: if only we could, we would surely have come forth with you. They destroy their own souls; and Allah knoweth that verily they are liars. 42
