(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 God, your true Lord; and when truth is gone what is left but error? So why do you turn away? 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: "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 Ask them: 'Are there among ones whom you associate with Allah in His divinity those who can guide to the truth? Say: 'It is Allah alone Who guides to the truth.' Then, who is more worthy to be followed - He Who guides to the truth, or he who cannot find the right way unless others guide him to it? What is wrong with you? How ill do you judge! 35 Most of them follow nothing except conjecture. But conjecture does not help against the truth. Allah knows the things they do. 36 This Koran could not have been forged apart from God; but it is a confirmation of what is before it, and a distinguishing of the Book, wherein is no doubt, from the Lord of all Being. 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 On the contrary, they denied the thing the knowledge of which they could not master, whereas they have not yet seen its outcome; similarly those before them had denied, therefore see what sort of fate befell the unjust! 39 And of them is he who believeth therein, and of them is he who believeth not therein, and thy Lord is Best Aware of the corrupters. 40
