What has happened to you, O believers, that when you are asked to set out in the cause of God your feet begin to drag? Do you find the life of the world so pleasing that you forget the life to come? Yet the profit of the life of this world is but meagre as compared to the life to come. 38 If you do not migrate, He will afflict you with a painful punishment and bring other people in your stead and you will not be able to harm Him in the least; and Allah is Able to do all things. 39 It will matter little if you do not help the Prophet, for Allah surely helped him when the unbelievers drove him out of his home and he was but one of the two when they were in the cave, and when he said to his companion: "Do not grieve. Allah is with us." Then Allah caused His tranquillity to descend upon him, and supported him with hosts you did not see, He humbled the word of the unbelievers. As for Allah's Word, it is inherently uppermost. Allah is All-Powerful, 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 Were it a gain at hand or a short journey, they would have surely followed you, but the distance seemed too far to them. Still they will swear by Allah: "If only we could, we would surely have gone forth with you." They merely bring ruin upon themselves. Allah knows well that they are liars. 42
