O People who Believe! What is the matter with you, that when it is said to you, “Migrate in Allah's cause”, you sit on the ground with heaviness? Have you preferred this worldly life over the Hereafter? And the wealth of the life of this world, in comparison with the Hereafter, is but only a little. 38 Unless you go out (to strive), God will inflict grievous punishment on you, and bring other people in your place, and you will not be able to harm Him in the least, for God has the 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 Go forth, whether light or heavy, and strive with your wealth and your lives in the cause of Allah. That is better for you, if you only knew. 41 Had the gain been immediate or the journey shorter, they (hypocrites) would certainly have followed you, (Muhammad), but it was too far for them. They will swear by God, "Had we had the ability, we would certainly have marched with you." They destroy only themselves and God knows that they are lying. 42
