(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 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 thy Sustainer's word proved true with regard to such as are bent on sinful doings: they will not believe 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: 'Do any of your partners guide you to the truth' Say: 'Allah, He guides to the truth. Who then is worthier to be followed He who guides to the truth or he who cannot guide unless he (himself) is guided? What is the matter with you, how then can you judge' 35 But most of them follow nothing but fancy: truly fancy can be of no avail against truth. Verily Allah is well aware of all that 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 (of the Prophet) that: "He has composed it?" Say to them: "Bring a Surah like this, and call anyone apart from God you can (to help you), if what you say is true." 38 They have belied that which they did not understand of its knowledge, nor has its interpretation reached them. Those who were before also belied. But see how was the end of the harmdoers. 39 And of them is he who believes in it, and of them is he who does not believe in it, and your Lord best knows the mischief-makers. 40
