They are not [all] the same; among the People of the Scriptures is an ummat standing [in obedience], reciting the verses of Allah during periods of the night and prostrating [in salat]. They believe in Allah and the Last Day, and they enjoin what is good and forbid what is evil and hasten to good deeds. And those are among the righteous. They will never be denied the reward for any good they have done. And Allah is All Knowing of those who are righteous.
