O you who believe! What is the matter with you, that when you are asked to march forth in the Cause of Allah (i.e. Jihad) you cling heavily to the earth? Are you pleased with the life of this world rather than the Hereafter? But little is the enjoyment of the life of this world as compared with the Hereafter. 38 Unless ye go forth, He will punish you with a grievous penalty, and put others in your place; but Him ye would not harm in the least. For Allah hath 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 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 it been an easy gain and a moderate trip, the hypocrites would have followed you, but distant to them was the journey. And they will swear by Allah, "If we were able, we would have gone forth with you," destroying themselves [through false oaths], and Allah knows that indeed they are liars. 42
