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 And assuredly We have raised in every community an apostle saying: worship Allah and avoid the devil. Then of them were some whom Allah guided, and of them were some upon whom the straying was justified. Wherefore travel about on the earth, and look on what wise hath been the end of the disbelievers. 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 have sworn by God the most earnest oaths God will never raise up him who dies; nay, it is a promise binding upon Him, but most men know not, 38 This will be in order that he may manifest unto them that wherein they differ, and that those who disbelieved should come to know that they had been liars. 39 When We want to bring something into existence, Our command is, "Exist," and it comes into existence. 40
