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 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 excepting by some mercy of thy Lord; surly His favour to thee is great. 87 Say: "If the mankind and the jinns were together to produce the like of this Quran, they could not produce the like thereof, even if 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 say: "We shall not believe in thee, until 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 make the heaven fall upon us in fragments as you have claimed or you bring Allah and the angels before [us] 92 "Or thou have a house adorned with gold, or thou mount a ladder right into the skies. No, we shall not even believe in thy mounting until thou send down to us a book that we could read." Say: "Glory to my Lord! Am I aught but a man,- a messenger?" 93
