Those who reject Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), We shall gradually seize them with punishment in ways they perceive not. 182 I give them rein (for) lo! My scheme is strong. 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 184 Or have they not considered the dominion of the heaven and of the earth, and what things God has created, and that it may be their term is already nigh? In what manner of discourse then will they after this believe? 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 concerning the Hour, when will its coming be? Say: 'The knowledge of it is with my Lord alone: none but He will disclose it at its time. That will weigh heavily on the heavens and the earth; and it shall not come to you other than all of a sudden.' They ask you - as if you are eagerly inquisitive about it - concerning it. Say to them: 'The knowledge of it is with none except Allah. But most people are unaware of this reality.' 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
