(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 Such is Allah, your rightful Lord. What then is there after the truth but error? Whither away then are ye drifting! 32 Thus the word of thy Lord is realized against the ungodly that they believe not. 33 Say, "Are there of your 'partners' any who begins creation and then repeats it?" Say, "Allah begins creation and then repeats it, so how are you deluded?" 34 Ask: "Is there one among those you associate with God who can show the way to the truth?" Say: "It is God who shows the way to truth." Then who is more worthy of being followed -- He who guides to the truth, or he who cannot find the path until shown the way? What has happened to you that you judge in such a wise? 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 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 Or say they: He hath invented it? Say: Then bring a surah like unto it, and call (for help) on all ye can besides Allah, if ye are truthful. 38 Nay, they reject that of which they have no comprehensive knowledge, and the final sequel of it has not yet come to them; even thus did those before them reject (the truth); see then what was the end of the unjust. 39 And of them are some who will believe therein, and of them are some who will not believe therein; and thy Lord is the Best Knower of the corrupters. 40
