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 listed, We could surely take away that which We have revealed unto thee; then thou wilt not find in respect thereof against Us as trustee. 86 Except as a Mercy from your Lord. Verily! His Grace unto you (O Muhammad SAW) is ever great. 87 Say: 'If mankind and jinn combined together to produce the like of this Koran, they would never be able to produce one like it, not even if they were to help one another' 88 And We have certainly diversified for the people in this Qur'an from every [kind] of example, but most of the people refused [anything] except disbelief. 89 And they say, "We will not believe you until you break open for us from the ground a spring. 90 Or there be for thee a garden of date-palms and wine, and thou causest in the midst thereof rivers to gush forth. 91 "Or thou cause the sky to fall in pieces, as thou sayest (will happen), against us; or thou bring Allah and the angels before (us) face to face: 92 Or thou have a house of gold; or thou ascend up into heaven, and even then we will put no faith in thine ascension till thou bring down for us a book that we can read. Say (O Muhammad): My Lord be Glorified! Am I aught save a mortal messenger? 93
