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 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 the Word of your Lord is proved true against those who are disobedient. 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 And most of them follow not except assumption. Indeed, assumption avails not against the truth at all. Indeed, Allah is Knowing of what they do. 36 And it was not [possible] for this Qur'an to be produced by other than Allah, but [it is] a confirmation of what was before it and a detailed explanation of the [former] Scripture, about which there is no doubt, from the Lord of the worlds. 37 Or do they say [about the Prophet], "He invented it?" Say, "Then bring forth a surah like it and call upon [for assistance] whomever you can besides Allah, if you should be truthful." 38 In fact they arbitrarily rejected as false whatever they failed to comprehend and whose final sequel was not apparent to them. Likewise had their predecessors rejected the truth, declaring it falsehood. Do observe, then, what was the end of the wrong-doers. 39 And of them are some who will believe therein, and of them are some who will not believe therein; and thy Lord is the Best Knower of the corrupters. 40
