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 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 Say, "Are there of your 'partners' any who begins creation and then repeats it?" Say, "Allah begins creation and then repeats it, so how are you deluded?" 34 Say: "Is there of your (Allah's so-called) partners one that guides to the truth?" Say: "It is Allah Who guides to the truth. Is then He, Who gives guidance to the truth, more worthy to be followed, or he who finds not guidance (himself) unless he is guided? Then, what is the matter with you? How judge you?" 35 Most of them follow not but conjecture. Assuredly conjecture can by no means take the place of truth. Lo! Allah is Aware of what they do. 36 And this Qur'an is such that it could not be composed by any unless it be revealed from Allah. It is a confirmation of the revelation made before it and a detailed exposition of the Book. Beyond doubt it is from the Lord of the universe. 37 Or say they: He hath invented it? Say: Then bring a surah like unto it, and call (for help) on all ye can besides Allah, if ye are truthful. 38 Nay, they reject that of which they have no comprehensive knowledge, and the final sequel of it has not yet come to them; even thus did those before them reject (the truth); see then what was the end of the unjust. 39 And of them are those who believe in it, and of them are those who do not believe in it. And your Lord is most knowing of the corrupters 40
