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 (for this purpose) I will grant them respite. My design is incontrovertible. 183 Do they not ponder that their companion is far removed from insanity? In fact he is clearly a Herald of Warning. 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 None can guide those whom Allah leaves in error. He leaves them in their insolence, wandering blindly. 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 [O Prophet]: "It is not within my power to bring benefit to, or avert harm from, myself, except as God may please. And if I knew that which is beyond the reach of human perception, abundant good fortune - would surely have fallen to my lot, and no evil would ever have touched me. I am nothing but a warner, and a herald of glad tidings unto people who will believe." 188
