And those who deny Our revelations - step by step We lead them on from whence they know not. 182 And I respite them; certainly My Plan is strong. 183 Do they not reflect? Their companion is not seized with madness: he is but a perspicuous warner. 184 Have they, then, never considered [God's] mighty dominion over the heavens and the earth, and all the things that God has created, and [asked themselves] whether, perchance, the end of their own term might already have drawn nigh? In what other tiding, 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 about the Hour (Day of Resurrection): "When will be its appointed time?" Say: "The knowledge thereof is with my Lord (Alone). None can reveal its time but He. Heavy is its burden through the heavens and the earth. It shall not come upon you except all of a sudden." They ask you as if you have a good knowledge of it. Say: "The knowledge thereof is with Allah (Alone) but most of mankind know not." 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
