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 will give them time. Indeed, my plan is firm. 183 Do they not reflect that their companion has not unsoundness in mind; he is only a plain 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 will question thee concerning the Hour, when it shall berth. Say: 'The knowledge of it is only with my Lord; none shall reveal it at its proper time, but He. Heavy is it in the heavens and the earth; it will not come on you but suddenly!' They will question thee, as though thou art well-informed of it. Say: 'The knowledge of it is only with God, but most men know not.' 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
