Ask them: 'Who provides you with sustenance out of the heavens and the earth? Who holds mastery over your hearing and sight? Who brings forth the living from the dead and the dead from the living? Who governs all affairs of the universe?' They will surely say: 'Allah.' Tell them: 'Will you, then, not shun (going against reality)?" 31 seeing that He is God, your Sustainer, the Ultimate Truth? For, after the truth [has been forsaken,] what is there [left] but error? How, then, can you lose sight of the truth?" 32 Thus is the Word of thy Lord justified concerning those who do wrong: that they believe not. 33 Ask then, "Can any of your partner-gods originate creation, and then reproduce it?" Say, "It is God who originates creation and then restores it: how then are you so misled?" 34 Say: 'Is there any of your associates who guides to the truth?' Say: 'God -- He guides to the truth; and which is worthier to be followed -- He who guides to the truth, or he who guides not unless he is guided? What then ails you, how you judge?' 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 And this Quran is not such as could be forged by those besides Allah, but it is a verification of that which is before it and a clear explanation of the book, there is no doubt in it, 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 Aye! they have belied that of which the knowledge they comprehended not and of which the fulfilment hath not come to them. Likewise belied those who were before them; behold then in what wise hath been the end of the wrongdoers. 39 Of them there are some who believe therein, and some who do not: and thy Lord knoweth best those who are out for mischief. 40
