The idolators say, 'If God had willed we would not have served; apart from Him, anything, neither we nor our fathers, nor would we have forbidden, apart from Him, anything.' So did those before them; yet is aught for the Messengers, but to deliver the manifest Message? 35 And We certainly sent into every nation a messenger, [saying], "Worship Allah and avoid Taghut." And among them were those whom Allah guided, and among them were those upon whom error was [deservedly] decreed. So proceed through the earth and observe how was the end of the deniers. 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 swear emphatically in the name of God that God will not raise the dead. On the contrary, it is a promise incumbent on Him, though most men do not understand, 38 For (they fear) He might make what they differed about plain to them, and that the infidels may realise that they were liars. 39 The only words We say to a thing, when We desire it, is that We say to it 'Be,' and it is. 40
