And they estimated not Allah with an estimation due unto Him when they said: on no human being hath God sent down aught. Say thou: who sent down the Books wherewith Musa came, a light and a guidance unto mankind, which ye have made into separate parchments. Some of it ye disclose and much thereof ye conceal. And ye were taught that which ye knew not: neither ye nor your fathers. Say thou: Allah, and let them alone, sporting in their vain discourse. 91 And this is a Book We have revealed, blessed, verifying that which is before it, and that you may warn the metropolis and those around her; and those who believe in the hereafter believe in it, and they attend to their prayers constantly. 92 Who is more vile than he who slanders God of falsehood, or says: "Revelation came to me," when no such revelation came to him; or one who claims: "I can reveal the like of what has been sent down by God?" If you could see the evil creatures in the agony of death with the angels thrusting forward their hands (saying): "Yield up your souls: This day you will suffer ignominious punishment for uttering lies about God and rejecting His signs with arrogance." 93 And now you have returned to Us, alone as We created you at first, leaving behind all that We gave you. Nor do We see with you your intercessors, those you claimed were your partners with God. The link between you is cut and that which you presumed has failed you. 94
