(Muhammad), ask them, "Who gives you sustenance from the heavens and earth, who truly possesses (your) hearing and seeing abilities, who brings the living out of the dead and the dead out of the living and who regulates (the whole Universe)? They will reply, "God." Ask them, "Why, then, do you not have fear of Him?" 31 That is God, your true Lord. What is there, besides the truth, but error? How then can you turn away?" 32 Thus is the Word of your Lord justified against those who rebel (disobey Allah) that they will not believe (in the Oneness of Allah and in Muhammad SAW as the Messenger of Allah). 33 Say: 'Is there any of your associates who originates creation, then brings it back again?' Say: 'God -- He originates creation, then brings it back again; so how are you perverted?' 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 And most of them follow nothing but conjecture. Certainly, conjecture can be of no avail against the truth. Surely, Allah is All-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 Or do they say: He has forged it? Say: Then bring a chapter like this and invite whom you can besides Allah, if you are truthful. 38 On the contrary, they denied the thing the knowledge of which they could not master, whereas they have not yet seen its outcome; similarly those before them had denied, therefore see what sort of fate befell the unjust! 39 Some of them believe in the Quran and others do not. Your Lord knows best the evil doers. 40
