The idolaters say: 'Had Allah willed, neither we nor our fathers would have worshipped anything other than Him, nor would we have forbidden anything without Him', as such did those before them. Yet what should Messengers do but give a clear deliverance? 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 Though thou art ever so eager to guide them, God guides not those whom He leads astray; they have no helpers. 37 And they swear by Allah their strongest oaths [that] Allah will not resurrect one who dies. But yes - [it is] a true promise [binding] upon Him, but most of the 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
