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 ye go not forth He will afflict you with a painful doom, and will choose instead of you a folk other than you. Ye cannot harm Him at all. Allah is Able to do 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 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
