They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given but little knowledge. 85 And if We please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us. 86 except for Mercy from your Lord; for His favor to you is great indeed. 87 Say: "If the whole of mankind and Jinns were to gather together to produce the like of this Qur'an, they could not produce the like thereof, even if they backed up each other with help and support. 88 And assuredly We have variously propounded for mankind in this Qur'an every kind of similitude, yet most men have refused everything except infidelity. 89 And they said, “We will not accept faith in you, until you cause a spring to gush forth from the earth for us.” 90 "Or you have a garden of date-palms and grapes, and cause rivers to gush forth in their midst abundantly; 91 “Or you cause the sky to fall upon us in pieces like you said – or bring Allah and the angels as Witness.” 92 Or, you come to possess a house of gold; or ascend to the skies, though we shall not believe in your having ascended till you bring down a book for us which we could read." Say: "Glory to my Lord. I am only man and a messenger." 93
