O you who believe! What (excuse) have you that when it is said to you: Go forth in Allah's way, you should incline heavily to earth; are you contented with this world's life instead of the hereafter? But the provision of this world's life compared with the hereafter is but little. 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 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, light-armed and heavy-armed, and strive with your wealth and your lives in the way of Allah! That is best for you if ye but knew. 41 Had it been a near adventure and an easy journey they had followed thee, but the distance seemed too far for them. Yet will they swear by Allah (saying): If we had been able we would surely have set out with you. They destroy their souls, and Allah knoweth that they verily are liars. 42
