They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 85 And if We so willed, We could indeed take away whatever We have revealed unto thee, and in that [state of need] thou wouldst find none to plead in thy behalf before Us. 86 Except for Mercy from thy Lord: for his bounty is to thee (indeed) great. 87 Proclaim, “If all mankind and jinns agree to bring an equivalent to the Qur’an, they will not be able to bring its equal – even if they were to help each other.” 88 And We have certainly diversified for the people in this Qur'an from every [kind] of example, but most of the people refused [anything] except disbelief. 89 And they say, "We will not believe you until you break open for us from the ground a spring. 90 or, until you own a garden of palms and vines and cause rivers to gush forth with abundant water in them; 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 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
