Ask them: 'Who provides you with sustenance out of the heavens and the earth? Who holds mastery over your hearing and sight? Who brings forth the living from the dead and the dead from the living? Who governs all affairs of the universe?' They will surely say: 'Allah.' Tell them: 'Will you, then, not shun (going against reality)?" 31 Such then is God, your true Lord; and when truth is gone what is left but error?

So what has happened to you? What sort of a judgement you impose!” 35 And most of them follow nothing but conjecture. Certainly, conjecture can be of no avail against the truth. Surely, Allah is All-Aware of what they do. 36 Now this Qur'an could not possibly have been devised by anyone save God: nay indeed, it confirms the truth of whatever there still remains [of earlier revelations] and clearly spells out the revelation [which comes] - let there be no doubt about it - from the Sustainer of all the worlds. 37 Do they say: 'He has forged it'. Say: 'Compose one chapter like it, and call upon whom you will, other than Allah (to help you), if what you say is true' 38 In fact, they deny what is beyond the reach of their knowledge, whose explanation has not reached them yet. So had those who have gone before them denied; but look at the fate of the unjust 39 Of them there are some who believe therein, and some who do not: and thy Lord knoweth best those who are out for mischief. 40
