Say, "Who provides for you from the heaven and the earth? Or who controls hearing and sight and who brings the living out of the dead and brings the dead out of the living and who arranges [every] matter?" They will say, "Allah," so say, "Then will you not fear Him?" 31 Such is Allah, your real Cherisher and Sustainer: apart from truth, what (remains) but error? How then are ye turned away? 32 Thus the word of your Lord has come into effect upon those who defiantly disobeyed - that they will not believe. 33 Say, "Are there of your 'partners' any who begins creation and then repeats it?" Say, "Allah begins creation and then repeats it, so how are you deluded?" 34 Ask them: 'Are there among ones whom you associate with Allah in His divinity those who can guide to the truth? Say: 'It is Allah alone Who guides to the truth.' Then, who is more worthy to be followed - He Who guides to the truth, or he who cannot find the right way unless others guide him to it? What is wrong with you? How ill do you judge! 35 For, most of them follow nothing but conjecture: [and,] behold, conjecture can never be a substitute for truth. Verily, God has full knowledge of all that they do. 36 And this Qur'an is not such as could be fabricated as against Allah. But it is a confirmation of that which is before it, and a detailing of the Decree, whereof there is no doubt, from the Lord of the worlds. 37 Do they say that the Messenger has himself composed the Qur'an? Say: 'In that case bring forth just one surah like it and call on all whom you can, except Allah, to help you if you are truthful. 38 Indeed, they are denying something which they cannot comprehend; the reality not yet having dawned on them. Likewise those before them rejected the truth. But see what was the end of the wrongdoers. 39 And of them is he who believes in it, and of them is he who does not believe in it, and your Lord best knows the mischief-makers. 40
