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 aid the Prophet - Allah has already aided him when those who disbelieved had driven him out [of Makkah] as one of two, when they were in the cave and he said to his companion, "Do not grieve; indeed Allah is with us." And Allah sent down his tranquillity upon him and supported him with angels you did not see and made the word of those who disbelieved the lowest, while the word of Allah - that is the highest. And Allah is Exalted in Might and Wise. 40 Whether lightly or heavily, march on and fight for the Way of Allah, with your wealth and your persons. This will be best for you, if you but knew. 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
