Ask them: 'Who provides you with sustenance out of the heavens and the earth? Who holds mastery over your hearing and sight? Who brings forth the living from the dead and the dead from the living? Who governs all affairs of the universe?' They will surely say: 'Allah.' Tell them: 'Will you, then, not shun (going against reality)?" 31 That is God, your true Lord. What is there, besides the truth, but error? How then can you turn away?" 32 Thus is the word of thy Lord proved true against those who rebel: Verily they will not believe. 33 Ask them: "Is there among the partners (you ascribe to God) one who first originates then reverts it? Say: "It is God alone who first creates and then reverts it. So where do you stray?" 34 Say: Is there any of your associates who guides to the truth? Say: Allah guides to the truth. Is He then Who guides to the truth more worthy to be followed, or he who himself does not go aright unless he is guided? What then is the matter with you; how do you judge? 35 Most of the unbelievers follow only conjecture which certainly cannot serve as a substitute for the Truth. God knows well what they do. 36 This Qur'an is not such (a writ) as could be composed by anyone but God. It confirms what has been revealed before, and is an exposition of (Heaven's) law. Without any doubt it's from the Lord of all the worlds. 37 Do they say that Muhammad has invented it? (Muhammad), tell them, "If your claim is true, compose only one chapter like it and call on anyone besides God for help. 38 Nay, they deny that; the knowledge whereof they could not compass and whereof the interpretation has not yet come unto them. Thus those before them did deny. Then see what was the end of the Zalimun (polytheists and wrong-doers, etc.)! 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
