O you who have been given the Book! believe that which We have revealed, verifying what you have, before We alter faces then turn them on their backs, or curse them as We cursed the violaters of the Sabbath, and the command of Allah shall be executed.

And Musa said: Our Lord! surely Thou hast given to Firon and his chiefs finery and riches in this world's life, to this end, our Lord, that they lead (people) astray from Thy way: Our Lord! destroy their riches and harden their hearts so that they believe not until they see the painful punishment.
