Ask them: 'Who provides you with sustenance out of the heavens and the earth? Who holds mastery over your hearing and sight? Who brings forth the living from the dead and the dead from the living? Who governs all affairs of the universe?' They will surely say: 'Allah.' Tell them: 'Will you, then, not shun (going against reality)?" 31 Such is Allah, your rightful Lord. What then is there after the truth but error? Whither away then are ye drifting! 32 Thus does the word of your Lord prove true against those who transgress that they do not believe. 33 Ask them: "Is there among the partners (you ascribe to God) one who first originates then reverts it? Say: "It is God alone who first creates and then reverts it. So where do you stray?" 34 Say: 'Is there any of your associates who guides to the truth?' Say: 'God -- He guides to the truth; and which is worthier to be followed -- He who guides to the truth, or he who guides not unless he is guided? What then ails you, how you judge?' 35 And the most of them follow only surmise, and surmise avails naught against truth. Surely God 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 Or say they: He hath invented it? Say: Then bring a surah like unto it, and call (for help) on all ye can besides Allah, if ye are truthful. 38 Nay, they deny that; the knowledge whereof they could not compass and whereof the interpretation has not yet come unto them. Thus those before them did deny. Then see what was the end of the Zalimun (polytheists and wrong-doers, etc.)! 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
