Say: "Who is it that sustains you (in life) from the sky and from the earth? or who is it that has power over hearing and sight? And who is it that brings out the living from the dead and the dead from the living? and who is it that rules and regulates all affairs?" They will soon say, "Allah". Say, "will ye not then show piety (to Him)?" 31 Such, then, is Allah, your true Lord. And what is there after truth but error? How, then, are you being turned away? 32 Thus the word of your Lord about those who disobey comes true, 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: "Does any of those beings to whom you ascribe a share in God's divinity guide unto the truth?" Say: "It is God [alone] who guides unto the truth. Which, then, is more worthy to be followed - He who guides unto the truth, or he who cannot find the right way unless he is guided? What, then, is amiss with you and your judgment?" 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 And this Quran is not such as could be forged by those besides Allah, but it is a verification of that which is before it and a clear explanation of the book, there is no doubt in it, from the Lord of 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 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 them there are some who believe therein, and some who do not: and thy Lord knoweth best those who are out for mischief. 40
