They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given but little knowledge. 85 If it were Our Will, We could take away that which We have sent thee by inspiration: then wouldst thou find none to plead thy affair in that matter as against Us,- 86 Except as a Mercy from your Lord. Verily! His Grace unto you (O Muhammad SAW) is 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 they say: We will by no means believe in you until you cause a fountain to gush forth from the earth for us. 90 or, until you own a garden of palms and vines and cause rivers to gush forth with abundant water in them; 91 Or thou cause the heaven to fall upon us piecemeal, as thou hast pretended, or bring Allah and the angels as a warrant; 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
