O you who believe! What is the matter with you, that when you are asked to march forth in the Cause of Allah (i.e. Jihad) you cling heavily to the earth? Are you pleased with the life of this world rather than the Hereafter? But little is the enjoyment of the life of this world as compared with the Hereafter. 38 If you march not forth, He will punish you with a painful torment and will replace you by another people, and you cannot harm Him at all, and Allah is Able to do 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 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 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
