(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 seeing that He is God, your Sustainer, the Ultimate Truth? For, after the truth [has been forsaken,] what is there [left] but error? How, then, can you lose sight of the truth?" 32 Thus the word of thy Lord is realized against the ungodly that they believe not. 33 Say: 'Is there any of your associates who originates creation, then brings it back again?' Say: 'God -- He originates creation, then brings it back again; so how are you perverted?' 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 follow nothing except conjecture. But conjecture does not help against the truth. Allah knows the things 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 [about the Prophet], "He invented it?" Say, "Then bring forth a surah like it and call upon [for assistance] whomever you can besides Allah, if you should be truthful." 38 Rather, they have denied that which they encompass not in knowledge and whose interpretation has not yet come to them. Thus did those before them deny. Then observe how was the end of the wrongdoers. 39 And of them is he who believeth therein, and of them is he who believeth not therein, and thy Lord is Best Aware of the corrupters. 40
