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 And I grant them respite; surely My scheme is effective. 183 Have they not pondered that their companion [i.e. the Prophet Muhammad] is not afflicted with insanity? 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 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 Tell them: "I am not master of my own gain or loss but as God may please. If I had the knowledge of the Unknown I would have enjoyed abundance of the good, and no evil would have touched me. I am only a bearer of warnings and bringer of happy news for those who believe." 188
