They could not estimate Allah with estimation due to Him when they said: “Allah has sent down nothing to any human being”. Say: “Who then sent down the Book which is a Light and Guidance to mankind that Moses brought”. You have made (written) into paper sheets, disclosing and concealing much. You were taught what you did not nor your fathers know. Say: “Allah, then leave them to play with what they are busy in”.
And this (Qur'ân) is a Book We have sent down as Blessed, confirming that which is before it, so that you may warn the Mother of towns (Makkah) and those around it. They are constant in guarding their prayers (continue praying).
And who is more unjust than he who forges a lie against Allah, or says: “It has been revealed to me while nothing has been revealed to him” and he who says: “I will send down the like of that which Allah has sent down”? And if you had seen when the wrong-doers shall be in the agonies of death and the angels shall spread forth their hands: ‘Give up your souls’; today shall you be recompensed with a torment of degradation because of what you used to utter against Allah other than the truth, and because you showed pride against His Verses.
And certainly you have come to Us alone as We created you at first, and you have left behind your backs all that We gave you. We do not see with you your intercessors about whom you asserted that they were associates in respect to you. Certainly the ties between you are cut off, and what you asserted is gone from you.
