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 seeing that He is God, your Sustainer, the Ultimate Truth? For, after the truth [has been forsaken,] what is there [left] but error? How, then, can you lose sight of the truth?" 32 Thus is thy Sustainer's word proved true with regard to such as are bent on sinful doings: 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 any of your associates who guides to the truth?' Say: 'God -- He guides to the truth; and which is worthier to be followed -- He who guides to the truth, or he who guides not unless he is guided? What then ails you, how you judge?' 35 And the most of them follow only surmise, and surmise avails naught against truth. Surely God knows the things 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 Do they say, "He has fabricated it?" Say, "Bring me one chapter like it. Call on whom you may besides God to help you, if what you say be true!" 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
