Those who associate [others with God] say, "If God had so willed we would not have worshipped anything besides Him, neither we nor our fathers, nor would we have forbidden anything without His sanction." So did those who went before them. The duty of the messengers is only to convey the message clearly. 35 And indeed, within every community have We raised up an apostle [entrusted with this message]: "Worship God, and shun the powers of evil!" And among those [past generations] were people whom God graced with His guidance, just as there was among them [many a one] who inevitably fell prey to grievous error: go, then, about the earth and behold what happened in the end to those who gave the lie to the truth! 36 Though you [Prophet] may be eager to guide them, God does not guide those whom He lets go astray, [because of their refusal to give a positive response to the truth]. They will have no supporters. 37 And they swear by Allah their strongest oaths [that] Allah will not resurrect one who dies. But yes - [it is] a true promise [binding] upon Him, but most of the people do not know. 38 (They must be raised up), in order that He may manifest to them the truth of that wherein they differ, and that the rejecters of Truth may realise that they had indeed (surrendered to) Falsehood. 39 When We decree a thing, We only say: 'Be' and it is. 40
