Say: Who gives you sustenance from the heaven and the earth? Or Who controls the hearing and the sight? And Who brings forth the living from the dead, and brings forth the dead from the living? And Who regulates the affairs? Then they will say: Allah. Say then: Will you not then guard (against evil)? 31 Such is Allah, your Lord in truth. So after the truth, what else can there be, save error? How then are you turned away? 32 This is how the Word of your Lord is proved concerning the sinful, so 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, "Does any of your partner-gods guide one to the Truth?" Say, "It is God who guides to the truth. Then, is He who guides to the truth more worthy to be followed or one who cannot find the way himself unless he be guided? What is the matter with you? How ill you judge!" 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 ever be invented in despite of Allah; but it is a confirmation of that which was before it and an exposition of that which is decreed for mankind - Therein is no doubt - from the Lord of the Worlds. 37 Do they say that Muhammad has invented it? (Muhammad), tell them, "If your claim is true, compose only one chapter like it and call on anyone besides God for help. 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 Some of them will believe in it [the Quran], while others will not. And your Lord is fully aware of the evil-doers. 40
