They have no true respect of God when they say, "God has not sent anything to a mortal being." (Muhammad), tell them, "Who revealed the Book containing a light and guidance for the people which Moses brought? You wrote down only some parts of the original on paper and hid much, even after having learnt from it, that which neither you nor your fathers knew." Tell them, "God has (revealed the Quran)," and then leave them alone to pursue their useless investigations. 91 This is a Book We have sent down, blessed and confirming that which was before it, and for thee to warn the Mother of Cities and those about her; and those who believe in the world to come believe in it, and watch over their prayers. 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 ye are come unto Us singly even as We had created you for the first time, and ye have left behind your backs that which We had granted unto you, and We see not along with you your intercessors who ye fancied were Our associates in respect of you as ye asserted. Now are the ties betwixt you severed and strayed from you is that which ye were wont to assert. 94
