Say: Who gives you sustenance from the heaven and the earth? Or Who controls the hearing and the sight? And Who brings forth the living from the dead, and brings forth the dead from the living? And Who regulates the affairs? Then they will say: Allah. Say then: Will you not then guard (against evil)? 31 Such then is Allah, your rightful Lord. After the Truth what is there saving error? How then are ye turned away! 32 Thus the Word of your Lord is proved true against those who are disobedient. They will not believe. 33 Say: Is there of your partners (whom ye ascribe unto Allah) one that produceth Creation and then reproduceth it? Say: Allah produceth Creation, then reproduceth it. How then, are ye misled! 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 Most of them follow nothing except conjecture. But conjecture does not help against the truth. Allah knows the things they do. 36 And this Quran is not such as could be forged by those besides Allah, but it is a verification of that which is before it and a clear explanation of the book, there is no doubt in it, from the Lord of the worlds. 37 And yet, they [who are bent on denying the truth] assert, "[Muhammad] has invented it!" Say [unto them]: "Produce, then, a surah of similar merit; and [to this end] call to your aid whomever you can, other than God, if what you say is true! 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
