O People of the Book! Believe in (that Book) which We have revealed (now to Our Beloved Muhammad, [blessing and peace be upon him]) which (originally) confirms the Book that is with you, before We disfigure (features of some) faces and turn them on to their rear, or cast on them a curse like the one that We cast on those (who disobeyed) in the case of Sabbath. And the Commandment of Allah is bound to be executed.
