O ye who believe! What aileth you that when it is said unto you: Go forth in the way of Allah, ye are bowed down to the ground with heaviness. Take ye pleasure in the life of the world rather than in the Hereafter? The comfort of the life of the world is but little in the Hereafter. 38 If you do not go forth, He will punish you with a painful punishment and replace you by another nation. You will in no way harm Him; for Allah has power over all things. 39 If you do not support him [Muhammad], know that God did support him when those who denied the truth expelled him when the two of them were in the cave, he [Muhammad] told his companion, "Do not worry; for God is with us." So God sent His tranquillity down on him and aided him with forces invisible to you and placed the word of those who disbelieved lowest, while God's word remained supreme. God is powerful and wise. 40 Whether lightly or heavily, march on and fight for the Way of Allah, with your wealth and your persons. This will be best for you, if you but knew. 41 Were it a gain near at hand, and an easy journey, they would have followed thee; but the distance was too far for them. Still they will swear by God, 'Had we been able, we would have gone out with you,' so destroying their souls; and God knows that they are truly liars. 42
