O People who Believe! What is the matter with you, that when it is said to you, “Migrate in Allah's cause”, you sit on the ground with heaviness? Have you preferred this worldly life over the Hereafter? And the wealth of the life of this world, in comparison with the Hereafter, is but only a little. 38 If you do not go forth, He will chastise you with a painful chastisement and bring in your place a people other than you, and you will do Him no harm; and Allah has 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 light and heavy, and strive hard in Allah's way with your property and your persons; this is better for you, if you know. 41 Were it a gain near at hand, and an easy journey, they would have followed thee; but the distance was too far for them. Still they will swear by God, 'Had we been able, we would have gone out with you,' so destroying their souls; and God knows that they are truly liars. 42
