The idolaters say: 'Had Allah willed, neither we nor our fathers would have worshipped anything other than Him, nor would we have forbidden anything without Him', as such did those before them. Yet what should Messengers do but give a clear deliverance? 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 If thou art solicitous for their guidance, then verily Allah guideth not whomsoever He sendeth astray, and for them there are 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 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 Indeed, Our word to a thing when We intend it is but that We say to it, "Be," and it is. 40
