(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 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 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 Many of them follow nothing but illusion; yet illusion cannot replace the reality. God verily knows what they do. 36 This Koran could not have been forged by other than Allah. It confirms what was before it; a distinguishing Book, in which there is no doubt, from the Lord 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 They call a lie something that is beyond the limit of their knowledge and whose interpretation has not yet been revealed. Some people who lived before them also called Our revelations lies. Consider how terrible was the end of the unjust people! 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
