They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 85 Had We wanted, We could have removed the Spirit through whom We sent you revelation. Then you would not have found anyone to intercede with Us for you 86 Except as a Mercy from your Lord. Verily! His Grace unto you (O Muhammad SAW) is ever great. 87 Say: "If all mankind and all invisible beings would come together with a view to producing the like of this Qur'an, they could not produce its like even though they were to exert all their strength in aiding one another!" 88 In this Quran, We have set out all kinds of examples for people, yet most of them persist in denying the truth. 89 And they say: "We shall not believe in you (O Muhammad SAW), until you cause a spring to gush forth from the earth for us; 90 "Or you have a garden of date-palms and grapes, and cause rivers to gush forth in their midst abundantly; 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 there be for thee a house of gold or thou mountest to the heaven, and we will by no means believe in thy mounting even until thou causest a book to be sent down to us, which we may read. Say thou: hallowed be my Lord! I am naught but a human being sent as an apostle. 93
