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)."

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.
