Believers, what is the matter with you that when you are asked to go forth in the cause of God, you cling slothfully to the land? Do you prefer the life of this world to the Hereafter? But little is the comfort of this life, compared to that of 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 help him, yet God has helped him already, when the unbelievers drove him forth the second of two, when the two were in the Cave, when he said to his companion, 'Sorrow not; surely God is with us.' Then God sent down on him His Shechina, and confirmed him with legions you did not see; and He made the word of the unbelievers the lowest; and God's word is the uppermost; God is All-mighty, All-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 it a gain at hand or a short journey, they would have surely followed you, but the distance seemed too far to them. Still they will swear by Allah: "If only we could, we would surely have gone forth with you." They merely bring ruin upon themselves. Allah knows well that they are liars. 42
