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 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 ye succour him not, then surely Allah hath succoured him when these who disbelieved drave him, the second of the two, when the twain were in a cave, and when he said unto his companion: grieve not, verily Allah is with us. Then Allah sent down His calm upon him and aided him with hosts whom ye saw not, and made the word of those who disbelieved nethermost, and the word of Allah! that is the uppermost. And Allah is Mighty, Wise. 40 Go forth, whether lightly or heavily equipped, and strive and struggle, with your goods and your persons, for the cause of God. That is better for you, if you only knew. 41 Had the gain been immediate or the journey shorter, they (hypocrites) would certainly have followed you, (Muhammad), but it was too far for them. They will swear by God, "Had we had the ability, we would certainly have marched with you." They destroy only themselves and God knows that they are lying. 42
