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 do not go forth, He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all. And Allah is over all things competent. 39 If ye help him not, still Allah helped him when those who disbelieve drove him forth, the second of two; when they two were in the cave, when he said unto his comrade: Grieve not. Lo! Allah is with us. Then Allah caused His peace of reassurance to descend upon him and supported him with hosts ye cannot see, and made the word of those who disbelieved the nethermost, while Allah's Word it was that became the uppermost. Allah is Mighty, Wise. 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 the gain been immediate and the journey shorter, they would have followed you: but the distance seemed too great for them. Yet they will swear by God, "Had we been able, we would have gone out with you." They bring ruin upon themselves. God knows that they are surely lying. 42
