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 This is how the Word of your Lord is proved concerning the sinful, so 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 thou: is there any of your associate-gods who guideth you to the truth! Say thou: Allah guideth unto the truth. Is He, then, who guideth to the truth more worthy to be followed, or one who findeth not the guidance unless he is guided. What aileth ye then? How ill ye judge! 35 For, most of them follow nothing but conjecture: [and,] behold, conjecture can never be a substitute for truth. Verily, God has full knowledge of all that they do. 36 No one could have composed this Quran besides God. This confirms the existing Book (the Bible) and explains itself. There is no doubt that it is from the Lord of the Universe. 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 Rather, they have denied that which they encompass not in knowledge and whose interpretation has not yet come to them. Thus did those before them deny. Then observe how was the end of the wrongdoers. 39 Some of them will believe in it, some will not. Your Lord knows the transgressors well. 40
