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 march for His cause, He will afflict your with a painful punishment and replace you by another nation and your (destruction) will not harm Him at all. God has power over all things. 39 If you do not help him (Prophet Mohammed – peace and blessings be upon him), Allah has helped him – when he had to go forth due to the mischief of the disbelievers, just as two men* – when they were in the cave, when he was saying to his companion “Do not grieve; indeed Allah is with us”; then Allah caused His calm to descend upon him and helped him with armies you did not see, and disgraced the word of the disbelievers; and Allah’s Word is supreme; and Allah is the Almighty, the Wise. (* The Holy Prophet migrated only with S. Abu Bakr (who later became the first caliph) as his sole companion.) 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 (O Prophet), had the gain been close at hand, and easy the journey, they would surely have followed you; but hard was the journey and long the going. Even then they swear by God (and say): "If we had the strength we would surely have gone out with you." They are only ruining themselves, for God is aware they lie. 42
