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 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 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 [He will resurrect them] to the end that He might make clear unto them all whereon they [now] hold divergent views, and that they who are bent on denying the truth [of resurrection] might come to know that they were liars. 39 Indeed, Our word to a thing when We intend it is but that We say to it, "Be," and it is. 40
