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 For though I give them rein for a while, My strategy is sure. 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 Whoever Allah sends astray - there is no guide for him. And He leaves them in their transgression, wandering blindly. 186 They ask you (Muhammad), "When will the Day of Judgment be?" Tell them, "My Lord knows best. It is He who has appointed its time. It will be a grave hour both in the heavens and the earth. It will only approach you suddenly." They say, "It seems that you know about the coming of the Day of Judgment." Tell them, "Only God knows about it and most people do not know." 187 Say: 'I have no power to profit for myself; or hurt, but as God will. Had I knowledge of the Unseen I would have acquired much good, and evil would not have touched me. I am only a warner, and a bearer of good tidings, to a people believing.' 188
