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 And this is a Book which We have sent down, bringing blessings, and confirming (the revelations) which came before it: that thou mayest warn the mother of cities and all around her. Those who believe in the Hereafter believe in this (Book), and they are constant in guarding their prayers. 92 Who are more unjust than those who ascribe lies to God or say that God has sent them revelations when nothing has been sent to them, or those who say that they can also bring down (from heaven) a book like that which God has revealed? Would that you could see the unjust in the agonies of death when the angels will come forward with their hands outstretched to take their souls out of their bodies and say, "This is the day when you will face humiliating torment for the falsehood that you ascribed to God and for your contemptuously disregarding of His revelations." 93 And certainly you have come to Us alone as We created you at first, and you have left behind your backs the things which We gave you, and We do not see with you your intercessors about whom you asserted that they were (Allah's) associates in respect to you; certainly the ties between you are now cut off and what you asserted is gone from you. 94
