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 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 most binding oaths (that) Allah will not raise up him who dieth. Nay, but it is a promise (binding) upon Him in truth, but most of mankind know not, 38 In order that He may make clear to them the matter in which they differed, and the disbelievers 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
