(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 Thus is God your true Lord. In the absence of truth there is nothing but falsehood. Then where are you turning? 32 Thus the Word of your Lord is proved true against those who are disobedient. 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, "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 them only follow conjectures; and surely conjecture can be no substitute for truth. Allah is well aware of whatever 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 And yet, they [who are bent on denying the truth] assert, "[Muhammad] has invented it!" Say [unto them]: "Produce, then, a surah of similar merit; and [to this end] call to your aid whomever you can, other than God, if what you say is true! 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 of them is he who believeth therein, and of them is he who believeth not therein, and thy Lord is Best Aware of the corrupters. 40
