O ye who believe! what is the matter with you, that, when ye are asked to go forth in the cause of Allah, ye cling heavily to the earth? Do ye prefer the life of this world to the Hereafter? But little is the comfort of this life, as compared with the Hereafter. 38 If ye go not forth He will afflict you with a painful doom, and will choose instead of you a folk other than you. Ye cannot harm Him at all. Allah is Able to do all things. 39 If you do not help him, (Muhammad), God has already helped him. When the unbelievers expelled him and he was one of the two people in the cave telling his friend, "Do not worry; God is with us," then God gave him confidence and supported him with an army which you did not see and He defeated the cause of the disbelievers and made His own cause stand supreme. God is Majestic and All-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
