(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 That is God, your true Lord. What is there, besides the truth, but error? How then can you turn away?" 32 Thus the word of your Lord has come into effect upon those who defiantly disobeyed - that they will not believe. 33 Ask then, "Can any of your partner-gods originate creation, and then reproduce it?" Say, "It is God who originates creation and then restores it: how then are you so misled?" 34 Say: Is there any of your associates who guides to the truth? Say: Allah guides to the truth. Is He then Who guides to the truth more worthy to be followed, or he who himself does not go aright unless he is guided? What then is the matter with you; how do you judge? 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 This Qur'an is not such (a writ) as could be composed by anyone but God. It confirms what has been revealed before, and is an exposition of (Heaven's) law. Without any doubt it's from the Lord of all the worlds. 37 And yet, they [who are bent on denying the truth] assert, "[Muhammad] has invented it!" Say [unto them]: "Produce, then, a surah of similar merit; and [to this end] call to your aid whomever you can, other than God, if what you say is true! 38 No; but they have cried lies to that whereof they comprehended not the knowledge, and whose interpretation has not yet come to them. Even so those that were before them cried lies; then behold how was the end of the evildoers! 39 And some of them believe in it, and some believe not in it. Thy Lord knows very well those who do corruption. 40
