They question you about the spirit. Say: 'The spirit is from the command of my Lord. Except for a little knowledge you have been given nothing' 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 (It is naught) save mercy from thy Lord. Lo! His kindness unto thee was ever 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 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 there be for thee a garden of date-palms and wine, and thou causest in the midst thereof rivers to gush forth. 91 or till thou makest heaven to fall, as thou assertest, on us in fragments, or thou bringest God and the angels as a surety, 92 Or you have a house of gold or you ascend into the sky. And [even then], we will not believe in your ascension until you bring down to us a book we may read." Say, "Exalted is my Lord! Was I ever but a human messenger?" 93
