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 is Allah, your rightful Lord. What then is there after the truth but error? Whither away then are ye drifting! 32 Thus is the Word of thy Lord justified concerning those who do wrong: that they believe not. 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: Is there any of your associates who guides to the truth? Say: Allah guides to the truth. Is He then Who guides to the truth more worthy to be followed, or he who himself does not go aright unless he is guided? What then is the matter with you; how do you judge? 35 Most of them only follow conjectures; and surely conjecture can be no substitute for truth. Allah is well aware of whatever they do. 36 This Quran is not such as could have been produced by anyone but God. It fulfills that [the predictions] which came before it and gives a fuller explanation of the [earlier] Revelations. There is no doubt about it: it is from the Lord of the Universe. 37 Do they say that Muhammad has invented it? (Muhammad), tell them, "If your claim is true, compose only one chapter like it and call on anyone besides God for help. 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 some of them believe in it, and some believe not in it. Thy Lord knows very well those who do corruption. 40
