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 willed, We could surely do away with that which We revealed to you. Then you would not find for yourself concerning it an advocate against 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 men and jinn should combine together to bring the like of this Quran, they could not bring the like of it, though some of them were aiders of others. 88 And assuredly We have variously propounded for mankind in this Qur'an every kind of similitude, yet most men have refused everything except infidelity. 89 They have said, "We shall never believe you until you cause a spring to gush forth from the earth, 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 cause the sky to fall into pieces on us - as you believe you can - or bring God and the angels face to face with us, 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
