(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 Lord in truth. So after the truth, what else can there be, save error? How then are you turned away? 32 Thus is the word of thy Lord proved true against those who rebel: Verily 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 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 [about the Prophet], "He invented it?" Say, "Then bring forth a surah like it and call upon [for assistance] whomever you can besides Allah, if you should be truthful." 38 Nay, they reject that of which they have no comprehensive knowledge, and the final sequel of it has not yet come to them; even thus did those before them reject (the truth); see then what was the end of the unjust. 39 And there are among them such as will in time come to believe in this [divine writ,] just as there are among them such as will never believe in it; and thy Sustainer is fully aware as to who are the spreaders of corruption. 40
