Those who associate [others with God] say, "If God had so willed we would not have worshipped anything besides Him, neither we nor our fathers, nor would we have forbidden anything without His sanction." So did those who went before them. The duty of the messengers is only to convey the message clearly. 35 For We assuredly sent amongst every People a messenger, (with the Command), "Serve Allah, and eschew Evil": of the People were some whom Allah guided, and some on whom error became inevitably (established). So travel through the earth, and see what was the end of those who denied (the Truth). 36 [Even] if you should strive for their guidance, [O Muhammad], indeed, Allah does not guide those He sends astray, and they will have no helpers. 37 They have sworn by God the most earnest oaths God will never raise up him who dies; nay, it is a promise binding upon Him, but most men know not, 38 so that He may make clear to them that whereon they were at variance, and that the unbelievers may know that they were truly liars. 39 Whenever We will anything to be, We but say unto it Our word "Be" - and it is. 40
