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 a Messenger in every community (to tell them): "Serve Allah and shun the Evil One." Thereafter Allah guided some of them while others were overtaken by error. Go about the earth, then, and observe what was the end of those who rejected the Messengers, calling them liars. 36 [As for those who are bent on denying the truth - ] though thou be ever so eager to show them the right way, [know that,] verily, God does not bestow His guidance upon any whom He judges to have gone astray; and such shall have none to succour them [on Resurrection Day]. 37 They swear their strongest oaths by God that God will never raise the dead to life -- nonetheless, it is a promise truly binding on Him, even though most people do not realize it -- 38 so that He may make clear to them that whereon they were at variance, and that the unbelievers may know that they were truly liars. 39 Our word for a thing when We intend it, is only that We say to it, Be, and it is. 40
