As for those who reject Our signs as false, We shall lead them, step by step, to their ruin without their even perceiving it. 182 I give them rein (for) lo! My scheme is strong. 183 Why will they not understand that their companion (Muhammad) is not possessed by jinn. (Muhammad) is only a (Divinely) authorized preacher. 184 Do they not look in the dominion of the heavens and the earth and all things that Allah has created, and that it may be that the end of their lives is near. In what message after this will they then believe? 185 No one can guide those whom God lets go astray: He leaves them blundering about in their arrogance. 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 have no power over any good or harm to myself except as Allah willeth. If I had knowledge of the unseen, I should have multiplied all good, and no evil should have touched me: I am but a warner, and a bringer of glad tidings to those who have faith." 188
