We gradually lead those who have called Our revelations mere lies, to destruction. Their destruction will be such that they will not even notice how it seized them. 182 And I give them rein: verily My contrivance is firm. 183 Do they not ponder that their companion is far removed from insanity? In fact he is clearly a Herald of Warning. 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 For those whom God lets go astray, there is no guide; and He shall leave them in their overweening arrogance, blindly stumbling to and fro. 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 have no power to profit for myself; or hurt, but as God will. Had I knowledge of the Unseen I would have acquired much good, and evil would not have touched me. I am only a warner, and a bearer of good tidings, to a people believing.' 188
