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 is the word of thy Lord proved true against those who rebel: Verily they will not believe. 33 Say thou: is there any of your associate-gods who originateth the creation and then repeateth it? Say thou: Allah originateth the creation and then shall repeat it. Whither away then are ye deviating? 34 Say: 'Do any of your partners guide you to the truth' Say: 'Allah, He guides to the truth. Who then is worthier to be followed He who guides to the truth or he who cannot guide unless he (himself) is guided? What is the matter with you, how then can you judge' 35 Most of them follow nothing but mere conjecture. But conjecture is of no use against the Truth. God is well aware of what they do. 36 Now this Qur'an could not possibly have been devised by anyone save God: nay indeed, it confirms the truth of whatever there still remains [of earlier revelations] and clearly spells out the revelation [which comes] - let there be no doubt about it - from the Sustainer of all 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 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 of them are some who will believe therein, and of them are some who will not believe therein; and thy Lord is the Best Knower of the corrupters. 40
