AND THEY will ask thee about [the nature of] divine inspiration. Say: "This inspiration [comes] at my Sustainer's behest; and [you cannot understand its nature, O men, since] you have been granted very little of [real] 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 thy Lord: for his bounty is to thee (indeed) great. 87 Say: Verily, though mankind and the jinn should assemble to produce the like of this Qur'an, they could not produce the like thereof though they were helpers one of another. 88 And certainly We have explained for men in this Quran every kind of similitude, but most men do not consent to aught but denying. 89 They say: "We shall not believe in thee, until thou cause a spring to gush forth for us from the earth, 90 or you (show) us that you have your own garden of palm trees and vines with flowing streams therein, 91 or till thou makest heaven to fall, as thou assertest, on us in fragments, or thou bringest God and the angels as a surety, 92 "Or thou have a house adorned with gold, or thou mount a ladder right into the skies. No, we shall not even believe in thy mounting until thou send down to us a book that we could read." Say: "Glory to my Lord! Am I aught but a man,- a messenger?" 93
