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 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 [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. 37 And they swear by God the most solemn of oaths that God would not raise him who dieth. Yea! it is a promise on Him incumbent but most of mankind know not. 38 This is in order that He may make clear to them that which they differed upon, and in order that those who disbelieve might know that they were indeed lying. 39 The only words We say to a thing, when We desire it, is that We say to it 'Be,' and it is. 40
