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 why do you turn away? 32 Thus the word of thy Lord is realized against the ungodly that they believe not. 33 Say: "Is there of your (Allah's so-called) partners one that originates the creation and then repeats it?" Say: "Allah originates the creation and then He repeats it. Then how are you deluded away (from the truth)?" 34 Say: "Of your 'partners' is there any that can give any guidance towards truth?" Say: "It is Allah Who gives guidance towards truth, is then He Who gives guidance to truth more worthy to be followed, or he who finds not guidance (himself) unless he is guided? what then is the matter with you? How judge ye?" 35 And most of them follow not except assumption. Indeed, assumption avails not against the truth at all. Indeed, Allah is Knowing 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 that Muhammad has invented it? (Muhammad), tell them, "If your claim is true, compose only one chapter like it and call on anyone besides God for help. 38 They call a lie something that is beyond the limit of their knowledge and whose interpretation has not yet been revealed. Some people who lived before them also called Our revelations lies. Consider how terrible was the end of the unjust people! 39 Some of them believe in the Quran and others do not. Your Lord knows best the evil doers. 40
