Say (unto them, O Muhammad): Who provideth for you from the sky and the earth, or Who owneth hearing and sight; and Who bringeth forth the living from the dead and bringeth forth the dead from the living; and Who directeth the course? They will say: Allah. Then say: Will ye not then keep your duty (unto Him)? 31 For that is Allah, your Lord, the Truth. And what can be beyond truth except error? So how are you averted? 32 Thus the word of your Lord has come into effect upon those who defiantly disobeyed - that they will not believe. 33 Say, "Are there of your 'partners' any who begins creation and then repeats it?" Say, "Allah begins creation and then repeats it, so how are you deluded?" 34 Say: Is there any of your associates who guides to the truth? Say: Allah guides to the truth. Is He then Who guides to the truth more worthy to be followed, or he who himself does not go aright unless he is guided? What then is the matter with you; how do you judge? 35 Most of the unbelievers follow only conjecture which certainly cannot serve as a substitute for the Truth. God knows well 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 Or do they say [about the Prophet], "He invented it?" Say, "Then bring forth a surah like it and call upon [for assistance] whomever you can besides Allah, if you should be truthful." 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 there are among them such as will in time come to believe in this [divine writ,] just as there are among them such as will never believe in it; and thy Sustainer is fully aware as to who are the spreaders of corruption. 40
