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 real Cherisher and Sustainer: apart from truth, what (remains) but error? How then are ye turned away? 32 The decree of your Lord that the evil-doers will not have faith has already been issued. 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 Ask: "Is there one among those you associate with God who can show the way to the truth?" Say: "It is God who shows the way to truth." Then who is more worthy of being followed -- He who guides to the truth, or he who cannot find the path until shown the way? What has happened to you that you judge in such a wise? 35 Most of them follow nothing except conjecture. But conjecture does not help against the truth. Allah knows the things they do. 36 And this Qur'an is such that it could not be composed by any unless it be revealed from Allah. It is a confirmation of the revelation made before it and a detailed exposition of the Book. Beyond doubt it is from the Lord of the universe. 37 Do they say that the Messenger has himself composed the Qur'an? Say: 'In that case bring forth just one surah like it and call on all whom you can, except Allah, to help you if you are truthful. 38 On the contrary, they denied the thing the knowledge of which they could not master, whereas they have not yet seen its outcome; similarly those before them had denied, therefore see what sort of fate befell the unjust! 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
