They ask thee concerning the Spirit (of inspiration). Say: "The Spirit (cometh) by command of my Lord: of knowledge it is only a little that is communicated to you, (O men!)" 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 (It is naught) save mercy from thy Lord. Lo! His kindness unto thee was ever great. 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 indeed We have fully explained to mankind, in this Quran, every kind of similitude, but most mankind refuse (the truth and accept nothing) but disbelief. 89 and so they say: "[O Muhammad,] we shall not believe thee till thou cause a spring to gush forth for us from the earth, 90 “Or you have a garden of date-palms and grapes, and you make gushing rivers to flow in it.” 91 or you cause the heavens to fall down on us in pieces, as you have claimed; or you bring God and the angels before us face to face; 92 or (show us) that you have a well adorned house of your own, or climb into the sky. We shall never believe that you have climbed into the sky until you bring us a book that we can read." Say, "All glory belongs to my Lord. Am I more than a mortal Messenger?" 93
