(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 God, your true Lord; and when truth is gone what is left but error? So why do you turn away? 32 Thus the word of thy Lord is realized against the ungodly 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 of your partners (whom ye ascribe unto Allah) one that leadeth to the Truth? Say: Allah leadeth to the Truth. Is He Who leadeth to the Truth more deserving that He should be followed, or he who findeth not the way unless he (himself) be guided. What aileth you? How judge ye? 35 And the most of them follow only surmise, and surmise avails naught against truth. Surely God knows the things they do. 36 No one could have composed this Quran besides God. This confirms the existing Book (the Bible) and explains itself. There is no doubt that 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 Aye! they have belied that of which the knowledge they comprehended not and of which the fulfilment hath not come to them. Likewise belied those who were before them; behold then in what wise hath been 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
