But those who deny Our signs - We will progressively lead them [to destruction] from where they do not know. 182 And I grant them respite; surely My scheme is effective. 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 184 Have they not considered the dominion of the heavens and the earth, and what things Allah hath created, and that it may be that their own term draweth nigh? In what fact after this will they believe? 185 Whomsoever Allah sends astray, none can guide him; and He lets them wander blindly in their transgressions. 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 (Muhammad), say, "I have no control over my benefits or sufferings, without the will of God. Had I known about the unseen, I would have gained much good and would have faced no suffering. I am only a warner and I preach the glad news to the believing people." 188
