Hypocrites stay behind
Say to those desert Arabs who stayed behind: “You will be summoned against a people of great might, you will fight them unless they surrender. If you obey, God will grant you a fine reward. But if you turn away, as you turned away before, He will punish you with a painful punishment.”
48:16Say unto those of the wandering Arabs who were left behind: Ye will be called against a folk of mighty prowess, to fight them until they surrender; and if ye obey, Allah will give you a fair reward; but if ye turn away as ye did turn away before, He will punish you with a painful doom.
