They ask you about the Spirit. Say, "The Spirit comes by the command of my Lord. You have been given very 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 (It is naught) save mercy from thy Lord. Lo! His kindness unto thee was ever great. 87 Say: "Surely if men and jinns get together to produce the like of this (Qur'an), they will not be able to produce the like of it, however they might assist one another. 88 And indeed We have illustrated all kinds of examples in the Qur’an for mankind – so most men did not accept, except to be ungrateful. 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 that there be a garden of palms and vines for you and then you cause rivers to abundantly flow forth through them; 91 or cause the sky to fall on us in pieces as you claimed, or bring Allah and the angels before us, face to face; 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
