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 We raised among every people a messenger who enjoined, "Worship God alone and shun the evil one." Then among them were some whom God guided and among them were others who became deserving of ruin. So travel across the earth and observe what was the end of those who rejected the messengers. 36 Even if you are eager to guide them, God does not surely guide those who have gone astray: They will have no one to help them. 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 (Through the resurrection) God wants to make a clear distinction between right and wrong and make the unbelievers know that they were liars. 39 And Our word unto a thing, when We intend it, is only that We say unto it: Be! and it is. 40
