(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 Such is Allah, your rightful Lord. What then is there after the truth but error? Whither away then are ye drifting! 32 The decree of your Lord that the evil-doers will not have faith has already been issued. 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 them follow nothing except conjecture. But conjecture does not help against the truth. Allah knows the things 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 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 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 among them is one who accepts faith in it, and among them is one who does not accept faith in it; and your Lord well knows the mischievous. 40
