(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 This then is Allah, your true Lord; and what is there after the truth but error; how are you then turned back? 32 Thus the word of your Lord has come into effect upon those who defiantly disobeyed - that they will not believe. 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 But most of them follow nothing but fancy: truly fancy can be of no avail against truth. Verily Allah is well aware of all that they do. 36 This Qur'an is not such as can be produced by other than Allah; on the contrary it is a confirmation of (revelations) that went before it, and a fuller explanation of the Book - wherein there is no doubt - from the Lord of the worlds. 37 Or do they say: He has forged it? Say: Then bring a chapter like this and invite whom you can besides Allah, if you are truthful. 38 In fact they arbitrarily rejected as false whatever they failed to comprehend and whose final sequel was not apparent to them. Likewise had their predecessors rejected the truth, declaring it falsehood. Do observe, then, what was the end of the wrong-doers. 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
