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 We pleased We could take away what We have revealed to you. Then you will not find any one to plead for it with Us, 86 Except for Mercy from thy Lord: for his bounty is to thee (indeed) great. 87 Say, "If mankind and the jinn gathered in order to produce the like of this Qur'an, they could not produce the like of it, even if they were to each other assistants." 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 they say: We will not put faith in thee till thou cause a spring 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, let chunks of sky fall over us, as you assert (you will); or, bring God and the angels as a surety; 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
