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 For We assuredly sent amongst every People a messenger, (with the Command), "Serve Allah, and eschew Evil": of the People were some whom Allah guided, and some on whom error became inevitably (established). So travel through the earth, and see what was the end of those who denied (the Truth). 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 They swear emphatically in the name of God that God will not raise the dead. On the contrary, it is a promise incumbent on Him, though most men do not understand, 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 When We will something to happen, all that We say is, "Be!" and it is. 40
