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 That then is God, your Lord, the True; what is there, after truth, but error? Then how are you turned about? 32 Thus the word of your Lord about those who disobey comes true, that they do not believe. 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 This Koran could not have been forged by other than Allah. It confirms what was before it; a distinguishing Book, in which there is no doubt, from the Lord of all the worlds. 37 Or do they say [about the Prophet], "He invented it?" Say, "Then bring forth a surah like it and call upon [for assistance] whomever you can besides Allah, if you should be truthful." 38 They have belied that which they did not understand of its knowledge, nor has its interpretation reached them. Those who were before also belied. But see how was the end of the harmdoers. 39 And of them there are some who believe therein, and of them there are some who believe not therein, and your Lord is All-Aware of the Mufsidun (evil-doers, liars, etc.). 40
