And (as to) those who reject Our communications, We draw them near (to destruction) by degrees from whence they know not. 182 For though I give them rein for a while, My strategy 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 Have they not looked into the realms of the heavens and the earth and all that God created, and seen that the end of their time might be near? What will they believe in if they do not believe in this? 185 For one whom Allah sends astray, there is none to guide him; and He leaves them to wander in their rebellion. 186 They ask you about the Hour (Day of Resurrection): "When will be its appointed time?" Say: "The knowledge thereof is with my Lord (Alone). None can reveal its time but He. Heavy is its burden through the heavens and the earth. It shall not come upon you except all of a sudden." They ask you as if you have a good knowledge of it. Say: "The knowledge thereof is with Allah (Alone) but most of mankind know not." 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
