And there is not a town but We will destroy it before the day of resurrection or chastise it with a severe chastisement; this is written in the Divine ordinance.

Say to those of the dwellers of the desert who were left behind: You shall soon be invited (to fight) against a people possessing mighty prowess; you will fight against them until they submit; then if you obey, Allah will grant you a good reward; and if you turn back as you turned back before, He will punish you with a painful punishment.
