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 If We pleased, We would certainly take away that which We have revealed to you, then you would find no guardian for you against Us, 86 except for Mercy from your Lord; for His favor to you is great indeed. 87 Say, "If all men and jinn gathered together to produce the like of this Quran, they could not produce one like it, however much they helped one another." 88 And verily We have displayed for mankind in this Qur'an all kind of similitudes, but most of mankind refuse aught save disbelief. 89 They have said, "We shall never believe you until you cause a spring to gush forth from the earth, 90 Or thou have a garden of date-palms and grapes, and cause rivers to gush forth therein abundantly; 91 Or you make the heaven fall upon us in fragments as you have claimed or you bring Allah and the angels before [us] 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
