Or lest you should say, `Had the Book been revealed to us we would surely have been better guided than they.' Now there has certainly come to you from your Lord (in the form of the Qur'ân) a clear evidence, an excellent guidance and a great mercy. Who then, is more unjust than he who cries lies to the revelations of Allâh and turns away from them? We will certainly award those who turn away from Our revelations an awful punishment, because of their having turned away.
