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 march not forth, He will punish you with a painful torment and will replace you by another people, and you cannot harm Him at all, and Allah is Able to do all things. 39 If you do not help (the Prophet, remember) God had helped him when the infidels had forced him to leave (and he was) one of two. When both of them were in the cave, he said to his companion: "Do not grieve, for God is with us." Then God sent divine peace on him, and invisible armies for his help, and made the unbelievers' purpose abject. Most exalted is God's word, for God is all-mighty and all-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 Were there a gear nigh and a journey moderate, they would have surely followed thee, but the distance seemed far unto them. And anon they will be swearing by Allah: if only we could, we would surely have come forth with you. They destroy their own souls; and Allah knoweth that verily they are liars. 42
