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 is Allah, your Lord in truth. So after the truth, what else can there be, save error? How then are you turned away? 32 Thus the word of thy Lord is realized against the ungodly that they believe not. 33 Ask them: "Is there among the partners (you ascribe to God) one who first originates then reverts it? Say: "It is God alone who first creates and then reverts it. So where do you stray?" 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 Most of them only follow conjectures; and surely conjecture can be no substitute for truth. Allah is well aware of whatever 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 Nay, but they are bent on giving the lie to everything the wisdom whereof they do not comprehend, and ere its inner meaning has become clear to them Even thus did those who lived before their time give the lie to the truth: and behold what happened in the end to those evildoers! 39 And some of them believe in it, and some believe not in it. Thy Lord knows very well those who do corruption. 40
