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 And verily We have raised in every nation a messenger, (proclaiming): Serve Allah and shun false gods. Then some of them (there were) whom Allah guided, and some of them (there were) upon whom error had just hold. Do but travel in the land and see the nature of the consequence for the deniers! 36 Though thou art ever so eager to guide them, God guides not those whom He leads astray; they have no helpers. 37 They solemnly swear by Allah that Allah will never raise the dead to life. No, surely the promise of Allah is binding upon Him, though most people do not know. 38 [It is] so He will make clear to them [the truth of] that wherein they differ and so those who have disbelieved may know that they were liars. 39 For to anything which We have willed, We but say the word, "Be", and it is. 40
