Say: The Spirit is by command of my Lord, and of knowledge ye have been vouchsafed but little. 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 Unless your Lord have mercy. His blessings on you are great indeed. 87 Say: 'If mankind and jinn combined together to produce the like of this Koran, they would never be able to produce one like it, not even if they were to help one another' 88 We have indeed turned about for men in this Koran every manner of similitude; yet most men refuse all but unbelief. 89 They said: "We shall not accept your Message until you cause a spring to gush forth for us from the earth; 90 Or [until] you have a garden of palm tress and grapes and make rivers gush forth within them in force [and abundance] 91 Or thou causest the heaven to fall upon us, as thou assertest, in pieces, or thou bringest God and the angels face to face. 92 Or you should have a house of gold, or you should ascend into heaven, and we will not believe in your ascending until you bring down to us a book which we may read. Say: Glory be to my Lord; am I aught but a mortal apostle? 93
