And those who associate others with Allah say, "If Allah had willed, we would not have worshipped anything other than Him, neither we nor our fathers, nor would we have forbidden anything through other than Him." Thus did those do before them. So is there upon the messengers except [the duty of] clear notification? 35 We raised among every people a messenger who enjoined, "Worship God alone and shun the evil one." Then among them were some whom God guided and among them were others who became deserving of ruin. So travel across the earth and observe what was the end of those who rejected the messengers. 36 Though thou art ever so eager to guide them, God guides not those whom He leads astray; they have no helpers. 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 is in order that He may make clear to them that which they differed upon, and in order that those who disbelieve might know that they were indeed lying. 39 And Our command for anything to occur, when We will it, is that We only say to it, “Be” – and it thereupon happens. 40
