They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given but 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 the mercy of your Lord; indeed His munificence upon you (O dear Prophet Mohammed – peace and blessings be upon him) is extremely 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 And verily We have displayed for mankind in this Qur'an all kind of similitudes, but most of mankind refuse aught save disbelief. 89 And they say: we shall by no means believe in thee until thou causest for us to gush forth from the earth a fountain. 90 or thou have a garden of date-palms and vines and cause rivers to gush forth in their midst in a sudden rush, 91 or, until you cause the sky to fall upon us in pieces, as you have claimed, or, as a surety bring Allah with the angels in front; 92 or that there come to be for you a house of gold, or that you ascend to the sky - though we shall not believe in your ascension (to the sky) - until you bring down a book for us that we can read." Say to them, (O Muhammad): "Holy is my Lord! Am I anything else than a human being, who bears a Message (from Allah)?" 93
