And those who deny Our revelations - step by step We lead them on from whence they know not. 182 I give them rein (for) lo! My scheme is strong. 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 No one can guide those whom God has caused to go astray and has left to continue blindly in their rebellion. 186 They ask thee concerning the Hour, when will its coming be? Say thou: knowledge thereof is with my Lord only: none shall disclose it at its time but He; heavy it is in the heavens and the earth; it shall not come upon you except on a sudden. They ask thee as though thou wert familiar therewith. Say thou: knowledge thereof is with Allah only; but most of men 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
