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 Respite will I grant unto them: for My scheme is strong (and unfailing). 183 Have they not reflected? No madness is in their comrade; he is naught but a plain warner. 184 Have they not looked into the realms of the heavens and the earth and all that God created, and seen that the end of their time might be near? What will they believe in if they do not believe in this? 185 Whomsoever Allah sendeth astray, no guide is then for him, and He letteth them wander perplexed in their exorbitance. 186 They ask you about the Hour and when it is to come. Say: 'None knows except my Lord. He alone will reveal it at the appointed time. It is heavy in the heavens and earth. It will not come to you but suddenly' They will question you, as though you had full knowledge of it. Say: 'Its knowledge is with Allah, though most people are unaware' 187 Say, "I myself have no power to benefit or do harm, save as God pleases. If I had knowledge of the unseen, I would have availed myself of an abundance of good, and no harm would have touched me. I am but a warner and a bearer of good tidings for those who will believe." 188
