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 Allah, your rightful Lord. After the Truth what is there saving error? How then are ye turned away! 32 Thus is the Word of thy Lord justified concerning those who do wrong: that they believe not. 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 And most of them do not follow (anything) but conjecture; surely conjecture will not avail aught against the truth; surely Allah is cognizant of what 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 that the Messenger has himself composed the Qur'an? Say: 'In that case bring forth just one surah like it and call on all whom you can, except Allah, to help you if you are truthful. 38 Aye! they have belied that of which the knowledge they comprehended not and of which the fulfilment hath not come to them. Likewise belied those who were before them; behold then in what wise hath been the end of the wrongdoers. 39 And of them there are some who believe therein, and of them there are some who believe not therein, and your Lord is All-Aware of the Mufsidun (evil-doers, liars, etc.). 40
