(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 then is Allah, your rightful Lord. After the Truth what is there saving error? How then are ye turned away! 32 Thus the word of your Lord has come into effect upon those who defiantly disobeyed - that they will not believe. 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 Say: "Of your 'partners' is there any that can give any guidance towards truth?" Say: "It is Allah Who gives guidance towards truth, is then He Who gives guidance to truth more worthy to be followed, or he who finds not guidance (himself) unless he is guided? what then is the matter with you? How judge ye?" 35 And most of them do not follow anything except assumptions; indeed assumption does not serve the least purpose (in place) of the truth; indeed Allah knows their deeds. 36 And this Qur'an is not such as could be fabricated as against Allah. But it is a confirmation of that which is before it, and a detailing of the Decree, whereof there is no doubt, 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 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 some of them believe in it, and some believe not in it. Thy Lord knows very well those who do corruption. 40
