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 him, (Muhammad), God has already helped him. When the unbelievers expelled him and he was one of the two people in the cave telling his friend, "Do not worry; God is with us," then God gave him confidence and supported him with an army which you did not see and He defeated the cause of the disbelievers and made His own cause stand supreme. God is Majestic and All-wise. 40 Go forth to war, whether it be easy or difficult [for you,] and strive hard in God's cause with your possessions and your lives: this is for your own good - if you but knew it! 41 If there had been immediate gain (in sight), and the journey easy, they would (all) without doubt have followed thee, but the distance was long, (and weighed) on them. They would indeed swear by Allah, "If we only could, we should certainly have come out with you": They would destroy their own souls; for Allah doth know that they are certainly lying. 42
