The idolators say, 'If God had willed we would not have served; apart from Him, anything, neither we nor our fathers, nor would we have forbidden, apart from Him, anything.' So did those before them; yet is aught for the Messengers, but to deliver the manifest Message? 35 We sent a Messenger to every nation, saying: 'Worship Allah and avoid the idols' Amongst them were some whom Allah guided, and some justly disposed to error. Travel in the land and see what was the end of those who belied (the Revelation and the prophets)! 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 They swear their strongest oaths by Allah, that Allah will not raise up those who die: Nay, but it is a promise (binding) on Him in truth: but most among mankind realise it not. 38 So that He might make manifest to them that about which they differ, and that those who disbelieve might know that they were liars. 39 When We decree a thing, We only say: 'Be' and it is. 40
