Some characteristics of People of the Book

And remember when God took a promise from the people of the Book to make its (truth) known to mankind, and not keep back any part of it, they set aside (the pledge), and sold it away for a little gain but how wretched the bargain that they made!

Think not that those who exult at what they have done, and who love to be praised for what they have not done, shall escape the punishment, for grievous indeed will be their doom.
