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 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 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 [It is] so He will make clear to them [the truth of] that wherein they differ and so those who have disbelieved may know that they were liars. 39 Yet when We will a thing We have only to say: "Be", and it is. 40
