And those who deny Our revelations - step by step We lead them on from whence they know not. 182 Respite will I grant unto them: for My scheme is strong (and unfailing). 183 Has it, then, never occurred to them that there is no madness whatever in [this] their fellowman? 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 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 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
