Say (unto them, O Muhammad): Who provideth for you from the sky and the earth, or Who owneth hearing and sight; and Who bringeth forth the living from the dead and bringeth forth the dead from the living; and Who directeth the course? They will say: Allah. Then say: Will ye not then keep your duty (unto 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 the Word of your Lord is proved true against those who are disobedient. They will not believe. 33 Say: 'Is there any (among) your associates who originates creation, then cause it to be revived yet again' Say: 'Allah, He originates creation, then revives it yet again. How is it that you are so perverted' 34 Say, "Are there of your 'partners' any who guides to the truth?" Say, "Allah guides to the truth. So is He who guides to the truth more worthy to be followed or he who guides not unless he is guided? Then what is [wrong] with you - how do you judge?" 35 Most of them follow not but conjecture. Assuredly conjecture can by no means take the place of truth. Lo! Allah is Aware of 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 Or do they say, 'Why, he has forged it'? Say: 'Then produce a sura like it, and call on whom you can, apart from God, if you speak truly.' 38 They have belied that which they did not understand of its knowledge, nor has its interpretation reached them. Those who were before also belied. But see how was the end of the harmdoers. 39 And of them is he who believes in it, and of them is he who does not believe in it, and your Lord best knows the mischief-makers. 40
