(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 That then is God, your Lord, the True; what is there, after truth, but error? Then how are you turned about? 32 Thus is thy Sustainer's word proved true with regard to such as are bent on sinful doings: 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 Say: "Of your 'partners' is there any that can give any guidance towards truth?" Say: "It is Allah Who gives guidance towards truth, is then He Who gives guidance to truth more worthy to be followed, or he who finds not guidance (himself) unless he is guided? what then is the matter with you? How judge ye?" 35 And most of them follow not except assumption. Indeed, assumption avails not against the truth at all. Indeed, Allah is Knowing 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 Or do they say, "He forged it"? say: "Bring then a Sura like unto it, and call (to your aid) anyone you can besides Allah, if it be ye speak the truth!" 38 No; but they have cried lies to that whereof they comprehended not the knowledge, and whose interpretation has not yet come to them. Even so those that were before them cried lies; then behold how was the end of the evildoers! 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
