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 And they swear by Allah their most binding oaths (that) Allah will not raise up him who dieth. Nay, but it is a promise (binding) upon Him in truth, but most of mankind know not, 38 That He may explain unto them that wherein they differ, and that those who disbelieved may know that they were liars. 39 (As for the possibility of resurrection, bear in mind that) whenever We do will something, We have to do no more than say: "Be", and it is. 40
