Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 and I respite them -- assuredly My guile is sure. 183 Has it, then, never occurred to them that there is no madness whatever in [this] their fellowman? He is only 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 sendeth astray, no guide is then for him, and He letteth them wander perplexed in their exorbitance. 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 do not have the power to acquire benefits or to avert harm from myself, except by the Will of Allah. Had I possessed knowledge of the unseen, I would have availed myself of much that is good, and no harm would have touched me. But I am only a warner and a bearer of glad tidings for a nation who believe. 188
