O Ye who believe! what aileth you that when it is said unto you: march forth in the way of Allah, ye are weighed down earthward? Are ye pleased with the life of the world rather than the Hereafter? whereas the enjoyment of the life of the world by the side of the Hereafter is but little. 38 If you do not migrate, He will afflict you with a painful punishment and bring other people in your stead and you will not be able to harm Him in the least; and Allah is Able to do 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 O believers, go out in the cause of God, (whether) light or heavy, and strive in the service of God, wealth and soul. This is better for you if you understand. 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
