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 If thou art anxious for their guidance, yet Allah guideth not such as He leaves to stray, and there is none to help them. 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 This will be in order that he may manifest unto them that wherein they differ, and that those who disbelieved should come to know that they had been liars. 39 Verily! Our Word unto a thing when We intend it, is only that We say unto it: "Be!" and it is. 40
