Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 And I give them rein: verily My contrivance is firm. 183 Why will they not understand that their companion (Muhammad) is not possessed by jinn. (Muhammad) is only a (Divinely) authorized preacher. 184 Do they see nothing in the government of the heavens and the earth and all that Allah hath created? (Do they not see) that it may well be that their terms is nigh drawing to an end? In what message after this will they then 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 [O Muhammad]: 'I have no power to benefit or harm myself except as Allah may please. And had I knowledge of the unseen, I should have amassed all kinds of good, and no evil would have ever touched me. I am merely a warner and the herald of glad tidings to those who have faith.' 188
