O ye who believe! what is the matter with you, that, when ye are asked to go forth in the cause of Allah, ye cling heavily to the earth? Do ye prefer the life of this world to the Hereafter? But little is the comfort of this life, as compared with the Hereafter. 38 If you do not go forth, He will chastise you with a painful chastisement and bring in your place a people other than you, and you will do Him no harm; and 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 Go forth, whether lightly or heavily equipped, and strive and struggle, with your goods and your persons, for the cause of God. 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
