They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given but little knowledge. 85 And if We please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us. 86 excepting by some mercy of thy Lord; surly His favour to thee is great. 87 Say: "If the mankind and the jinns were together to produce the like of this Quran, they could not produce the like thereof, even if they helped 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 said, “We will not accept faith in you, until you cause a spring to gush forth from the earth for us.” 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 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 have a house of adornable materials (like silver and pure gold, etc.), or you ascend up into the sky, and even then we will put no faith in your ascension until you bring down for us a Book that we would read." Say (O Muhammad SAW): "Glorified (and Exalted) be my Lord (Allah) above all that evil they (polytheists) associate with Him! Am I anything but a man, sent as a Messenger?" 93
