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 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 thy Lord is realized against the ungodly that they believe not. 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 Say: "Is there of your (Allah's so-called) partners one that guides to the truth?" Say: "It is Allah Who guides to the truth. Is then He, Who gives guidance to the truth, more worthy to be followed, or he who finds not guidance (himself) unless he is guided? Then, what is the matter with you? How judge you?" 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 This Qur'an is not such as can be produced by other than Allah; on the contrary it is a confirmation of (revelations) that went before it, and a fuller explanation of the Book - wherein there is no doubt - from the Lord of the worlds. 37 Do they say (of the Prophet) that: "He has composed it?" Say to them: "Bring a Surah like this, and call anyone apart from God you can (to help you), if what you say is true." 38 In fact, they deny what is beyond the reach of their knowledge, whose explanation has not reached them yet. So had those who have gone before them denied; but look at the fate of the unjust 39 Some believe in it, while others do not believe it. Your Lord knows well the corrupters. 40
