Surely they who disbelieve in the communications of Allah they shall have a severe chastisement; and Allah is Mighty, the Lord of retribution.

Or lest you should say: If the Book had been revealed to us, we would certainly have been better guided than they, so indeed there has come to you clear proof from your Lord, and guidance and mercy. Who then is more unjust than he who rejects Allah's communications and turns away from them? We will reward those who turn away from Our communications with an evil chastisement because they turned away.
