Or, lest you should say, "Had we had a Book (Scripture) revealed to us we should surely have been more guided than they;" But now there is come to them a manifest sign from their Lord, and a guidance and a mercy; who then is more unjust (does greater wrong) than he who denies the Signs (revelations) of Allah, and turns away from them? We will reward those who turn from our Signs with a severe punishment because of their turning.
