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 seeing that He is God, your Sustainer, the Ultimate Truth? For, after the truth [has been forsaken,] what is there [left] but error? How, then, can you lose sight of the truth?" 32 So the Word of your Lord is realized against the evildoers that they do not believe. 33 Ask them: 'Is there any among those whom you associate with Allah in His divinity who brings about the creation of all beings in the first instance and will then repeat it?' Tell them: 'It is Allah Who brings about the creation of all beings and will then repeat it. How are you, then, being misled? 34 Say, "Does any of your partner-gods guide one to the Truth?" Say, "It is God who guides to the truth. Then, is He who guides to the truth more worthy to be followed or one who cannot find the way himself unless he be guided? What is the matter with you? How ill you judge!" 35 Most of the unbelievers follow only conjecture which certainly cannot serve as a substitute for the Truth. God knows well what they do. 36 And it was not [possible] for this Qur'an to be produced by other than Allah, but [it is] a confirmation of what was before it and a detailed explanation of the [former] Scripture, about which there is no doubt, from the Lord of the worlds. 37 Or do they say, 'Why, he has forged it'? Say: 'Then produce a sura like it, and call on whom you can, apart from God, if you speak truly.' 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 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
