Indeed, my plan is firm. 183 Have they not reflected? No madness is in their comrade; he is naught but a plain warner. 184 Look they not at the governance of the heaven and the earth and whatsoever Allah hath created of aught, and at the fact that their term may have drawn nigh? In what discourse then will they, thereafter, believe! 185 Whomsoever Allah causes to err, there is no guide for him; and He leaves them alone in their inordinacy, blindly wandering on. 186 They ask you, [O Muhammad], about the Hour: when is its arrival? Say, "Its knowledge is only with my Lord. None will reveal its time except Him. It lays heavily upon the heavens and the earth. It will not come upon you except unexpectedly." They ask you as if you are familiar with it. Say, "Its knowledge is only with Allah, but most of the people do not know." 187 Say: 'I have no power to profit for myself; or hurt, but as God will. Had I knowledge of the Unseen I would have acquired much good, and evil would not have touched me. I am only a warner, and a bearer of good tidings, to a people believing.' 188
