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 Allah, your rightful Lord. After the Truth what is there saving error? How then are ye turned away! 32 Thus the word of your Lord is fulfilled concerning the transgressors that they shall not believe. 33 Say: "Is there of your (Allah's so-called) partners one that originates the creation and then repeats it?" Say: "Allah originates the creation and then He repeats it. Then how are you deluded away (from the truth)?" 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 For, most of them follow nothing but conjecture: [and,] behold, conjecture can never be a substitute for truth. Verily, God has full knowledge of all that they do. 36 Now this Qur'an could not possibly have been devised by anyone save God: nay indeed, it confirms the truth of whatever there still remains [of earlier revelations] and clearly spells out the revelation [which comes] - let there be no doubt about it - from the Sustainer of all the worlds. 37 Do they say: 'He has forged it'. Say: 'Compose one chapter like it, and call upon whom you will, other than Allah (to help you), 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 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
