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 For We assuredly sent amongst every People a messenger, (with the Command), "Serve Allah, and eschew Evil": of the People were some whom Allah guided, and some on whom error became inevitably (established). So travel through the earth, and see what was the end of those who denied (the Truth). 36 Even if you are eager to guide them, God does not surely guide those who have gone astray: They will have no one to help them. 37 They swear their strongest oaths by God that God will never raise the dead to life -- nonetheless, it is a promise truly binding on Him, even though most people do not realize it -- 38 In order that He may make clear to them the matter in which they differed, and the disbelievers may realise that they were liars. 39 Yet when We will a thing We have only to say: "Be", and it is. 40
