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 If you (O dear Prophet Mohammed – peace and blessings be upon him) desire for their guidance, then indeed Allah does not guide one whom He misleads, and they do not have any aides. 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 so that He may make clear to them that whereon they were at variance, and that the unbelievers may know that they were truly liars. 39 Yet when We will a thing We have only to say: "Be", and it is. 40
