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 is Allah, your rightful Lord. What then is there after the truth but error? Whither away then are ye drifting! 32 Thus is the Word of your Lord justified against those who rebel (disobey Allah) that they will not believe (in the Oneness of Allah and in Muhammad SAW as the Messenger of Allah). 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 of your (Allah's so-called) partners one that guides to the truth?" Say: "It is Allah Who guides to the truth. Is then He, Who gives guidance to the truth, more worthy to be followed, or he who finds not guidance (himself) unless he is guided? Then, what is the matter with you? How judge you?" 35 And most of them follow nothing but conjecture. Certainly, conjecture can be of no avail against the truth. Surely, Allah is All-Aware of what 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 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 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 Of them there are some who believe therein, and some who do not: and thy Lord knoweth best those who are out for mischief. 40
