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.

They are naught but names which you have named, you and your fathers; Allah has not sent for them any authority. They follow naught but conjecture and the low desires which (their) souls incline to; and certainly the guidance has come to them from their Lord.
