(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 then is God, your Lord, the True; what is there, after truth, but error? Then how are you turned about? 32 Thus is the Word of thy Lord justified concerning those who do wrong: 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, "Are there of your 'partners' any who guides to the truth?" Say, "Allah guides to the truth. So is He who guides to the truth more worthy to be followed or he who guides not unless he is guided? Then what is [wrong] 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 this Quran is not such as could be forged by those besides Allah, but it is a verification of that which is before it and a clear explanation of the book, there is no doubt in it, from the Lord of 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 Rather, they have denied that which they encompass not in knowledge and whose interpretation has not yet come to them. Thus did those before them deny. Then observe how was the end of the wrongdoers. 39 And of them there are some who believe therein, and of them there are some who believe not therein, and your Lord is All-Aware of the Mufsidun (evil-doers, liars, etc.). 40
