Ask them: "Who gives you food and sustenance from the skies and the earth? Or, who is the lord of ear and eye? And who brings forth the living from the dead, the dead from the living? And who directs all affairs?" They will say: "God." So tell them: "Why do you not fear Him?" 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 the word of your Lord has come into effect upon those who defiantly disobeyed - that they will not believe. 33 Say: Is there of your partners (whom ye ascribe unto Allah) one that produceth Creation and then reproduceth it? Say: Allah produceth Creation, then reproduceth it. How then, are ye misled! 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 Most of them follow not but conjecture. Assuredly conjecture can by no means take the place of truth. Lo! Allah is Aware of what they do. 36 Now this Qur'an could not possibly have been devised by anyone save God: nay indeed, it confirms the truth of whatever there still remains [of earlier revelations] and clearly spells out the revelation [which comes] - let there be no doubt about it - from the Sustainer 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 In fact they arbitrarily rejected as false whatever they failed to comprehend and whose final sequel was not apparent to them. Likewise had their predecessors rejected the truth, declaring it falsehood. Do observe, then, what was the end of the wrong-doers. 39 And of them is he who believeth therein, and of them is he who believeth not therein, and thy Lord is Best Aware of the corrupters. 40
