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 march forth, Allah will chastise you grievously and will replace you by another people, while you will in no way be able to harm Him. Allah has power over everything. 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, light and heavy! Struggle in God's way with your possessions and your selves; that is better for you, did you know. 41 Had it been a near advantage and a short journey, they would certainly have followed you, but the tedious journey was too long for them; and they swear by Allah: If we had been able, we would certainly have gone forth with you; they cause their own souls to perish, and Allah knows that they are most surely 42
