(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 Such then is Allah, your rightful Lord. After the Truth what is there saving error? How then are ye turned away! 32 So the Word of your Lord is realized against the evildoers that they do 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 And most of them do not follow (anything) but conjecture; surely conjecture will not avail aught against the truth; surely Allah is cognizant of what they do. 36 And it was not [possible] for this Qur'an to be produced by other than Allah, but [it is] a confirmation of what was before it and a detailed explanation of the [former] Scripture, about which there is no doubt, from the Lord of the worlds. 37 Or do they say, 'Why, he has forged it'? Say: 'Then produce a sura like it, and call on whom you can, apart from God, if you speak truly.' 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 will believe in it [the Quran], while others will not. And your Lord is fully aware of the evil-doers. 40
