(Muhammad), ask them, "Who gives you sustenance from the heavens and earth, who truly possesses (your) hearing and seeing abilities, who brings the living out of the dead and the dead out of the living and who regulates (the whole Universe)? They will reply, "God." Ask them, "Why, then, do you not have fear of Him?" 31 That is God, your true Lord. What is there, besides the truth, but error? How then can you turn away?" 32 This is how the Word of your Lord is proved concerning the sinful, so they will not believe. 33 Say: 'Is there any of your associates who originates creation, then brings it back again?' Say: 'God -- He originates creation, then brings it back again; so how are you perverted?' 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 Most of the unbelievers follow only conjecture which certainly cannot serve as a substitute for the Truth. God knows well what they do. 36 This Quran is not such as could have been produced by anyone but God. It fulfills that [the predictions] which came before it and gives a fuller explanation of the [earlier] Revelations. There is no doubt about it: it is from the Lord of the Universe. 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 Nay, they charge with falsehood that whose knowledge they cannot compass, even before the elucidation thereof hath reached them: thus did those before them make charges of falsehood: but see what was the end of those who did wrong! 39 Of them there are some who believe therein, and some who do not: and thy Lord knoweth best those who are out for mischief. 40
