(16:34) So they were struck by the evil consequences of what they did and were enveloped by what they used to ridicule. (16:35) And those who associate others with Allah say, "If Allah had willed, we would not have worshipped anything other than Him, neither we nor our fathers, nor would we have forbidden anything through other than Him." Thus did those do before them. So is there upon the messengers except [the duty of] clear notification? (16:36) 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. (16:37) [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. (16:38) 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. (16:39) [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. (16:40) Indeed, Our word to a thing when We intend it is but that We say to it, "Be," and it is.
