Say: Who gives you sustenance from the heaven and the earth? Or Who controls the hearing and the sight? And Who brings forth the living from the dead, and brings forth the dead from the living? And Who regulates the affairs? Then they will say: Allah. Say then: Will you not then guard (against evil)? 31 This then is Allah, your true Lord; and what is there after the truth but error; how are you then turned back? 32 Thus the word of thy Lord is realized against the ungodly that they believe not. 33 Say: "Of your 'partners', can any originate creation and repeat it?" Say: "It is Allah Who originates creation and repeats it: then how are ye deluded away (from the truth)?" 34 Say, "Are there of your 'partners' any who guides to the truth?" Say, "Allah guides to the truth. So is He who guides to the truth more worthy to be followed or he who guides not unless he is guided? Then what is [wrong] with you - how do 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 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 Some of them believe in the Quran and others do not. Your Lord knows best the evil doers. 40
