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: Is there of your partners (whom ye ascribe unto Allah) one that produceth Creation and then reproduceth it? Say: Allah produceth Creation, then reproduceth it. How then, are ye misled! 34 Say: "Does any of those beings to whom you ascribe a share in God's divinity guide unto the truth?" Say: "It is God [alone] who guides unto the truth. Which, then, is more worthy to be followed - He who guides unto the truth, or he who cannot find the right way unless he is guided? What, then, is amiss with you and your judgment?" 35 Many of them follow nothing but illusion; yet illusion cannot replace the reality. God verily knows 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 Do they say that the Messenger has himself composed the Qur'an? Say: 'In that case bring forth just one surah like it and call on all whom you can, except Allah, to help you if you are truthful. 38 Nay, but they are bent on giving the lie to everything the wisdom whereof they do not comprehend, and ere its inner meaning has become clear to them Even thus did those who lived before their time give the lie to the truth: and behold what happened in the end to those evildoers! 39 And some of them believe in it, and some believe not in it. Thy Lord knows very well those who do corruption. 40
