O ye who believe! What aileth you that when it is said unto you: Go forth in the way of Allah, ye are bowed down to the ground with heaviness. Take ye pleasure in the life of the world rather than in the Hereafter? The comfort of the life of the world is but little in 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 help (the Prophet, remember) God had helped him when the infidels had forced him to leave (and he was) one of two. When both of them were in the cave, he said to his companion: "Do not grieve, for God is with us." Then God sent divine peace on him, and invisible armies for his help, and made the unbelievers' purpose abject. Most exalted is God's word, for God is all-mighty and all-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 there been [a prospect of] immediate gain, and an easy journey, they would certainly have followed thee, [O Prophet:] but the distance was too great for them. And yet, [after your return, O believers,] they will swear by God, "Had we been able to do so, we would certainly have set out with you!" - [and by thus falsely swearing] they will be destroying their own selves: for God knows indeed that they are lying! 42
