Say, "Who provides [sustenance] for you from heaven and earth? Who is it who controls the ears and the eyes? Who brings forth the living from the dead, and the dead from the living? And who governs all affairs?" They will say, "God". Then say, "Will you not then 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 thy Lord is realized against the ungodly that they believe not. 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 Most of them only follow conjectures; and surely conjecture can be no substitute for truth. Allah is well aware of whatever 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 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 Nay, they reject that of which they have no comprehensive knowledge, and the final sequel of it has not yet come to them; even thus did those before them reject (the truth); see then what was the end of the unjust. 39 And of them are those who believe in it, and of them are those who do not believe in it. And your Lord is most knowing of the corrupters 40
