(Muhammad), ask them, "Who gives you sustenance from the heavens and earth, who truly possesses (your) hearing and seeing abilities, who brings the living out of the dead and the dead out of the living and who regulates (the whole Universe)? They will reply, "God." Ask them, "Why, then, do you not have fear of Him?" 31 That is God, your true Lord. What is there, besides the truth, but error? How then can you turn away?" 32 Thus does the word of your Lord prove true against those who transgress that they do 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 thou: is there any of your associate-gods who guideth you to the truth! Say thou: Allah guideth unto the truth. Is He, then, who guideth to the truth more worthy to be followed, or one who findeth not the guidance unless he is guided. What aileth ye then? How ill ye judge! 35 Many of them follow nothing but illusion; yet illusion cannot replace the reality. God verily knows what they do. 36 And this Qur'an is such that it could not be composed by any unless it be revealed from Allah. It is a confirmation of the revelation made before it and a detailed exposition of the Book. Beyond doubt it is from the Lord of the universe. 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 Indeed, they are denying something which they cannot comprehend; the reality not yet having dawned on them. Likewise those before them rejected the truth. But see what was the end of the wrongdoers. 39 Of those some will believe and others will not. Your Lord knows best the mischief-makers. 40
