The idolaters say: "If God had willed we would not have worshipped anything apart from Him, nor would our fathers have done, nor would we have forbidden any thing without His (leave)." So had the people done before them. Therefore it is binding on the prophets to convey the message in clearest terms. 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 If thou art anxious for their guidance, yet Allah guideth not such as He leaves to stray, and there is none to help them. 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 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 And Our word unto a thing, when We intend it, is only that We say unto it: Be! and it is. 40
