SAY: "Who is it that provides you with sustenance out of heaven and earth, or who is it that has full power over [your] hearing and sight? And who is it that brings forth the living out of that which is dead, and brings forth the dead out of that which is alive? And who is it that governs all that exists?" And they will [surely] answer: "[It is] God." Say, then: "Will you not, then, become [fully] conscious of Him 31 Such, then, is Allah, your true Lord. And what is there after truth but error? How, then, are you being turned away? 32 Thus the word of your Lord has come into effect upon those who defiantly disobeyed - that they will not believe. 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 (Muhammad), ask them, "Can any of your idols guide you to the Truth?" Say, "Only God guides to the Truth." Is the one who guides to the Truth a proper guide or one who himself cannot find guidance unless he is guided (by others)? What is wrong with you that you judge (so unjustly)? 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 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 In fact, they deny what is beyond the reach of their knowledge, whose explanation has not reached them yet. So had those who have gone before them denied; but look at the fate of the unjust 39 Some believe in it, while others do not believe it. Your Lord knows well the corrupters. 40
