Then you would not find for yourself concerning it an advocate against Us. 86 But on account of mercy from your Lord-- surely His grace to you is abundant. 87 Say, "If all human beings and jinn were to come together to bring the equivalent of this Quran, they could not do so, even if they all were to help each other. 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 They declare, "We will never believe in you until you cause a spring to flow for us from the earth; 90 or thou have a garden of date-palms and vines and cause rivers to gush forth in their midst in a sudden rush, 91 or thou cause the skies to fall down upon us in smithereens, as thou hast threatened, or [till] thou bring God and the angels face to face before us, 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
