But as for those who are bent on giving the lie to Our messages - We shall bring them low, step by step, without their perceiving how it came about: 182 And I give them rein: verily My contrivance is firm. 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 sends astray, none can guide him; and He lets them wander blindly in their transgressions. 186 They ask you [Prophet] about the Last Hour, "When will it come?" Say, "Knowledge about it rests only with my Lord; He alone will reveal when its time will come, it lies heavy on the heavens and the earth: it will suddenly overtake you." They will put questions to you as though you had full knowledge of it. Say, "Knowledge about it rests only with God, though most people do not realize it." 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
