But those who deny Our signs - We will progressively lead them [to destruction] from where they do not know. 182 For though I give them rein for a while, My strategy is sure. 183 Do they not reflect? Their companion is not seized with madness: he is but a perspicuous warner. 184 Have they not pondered deeply regarding the kingdom of the heavens and the earth, and whatever things Allah created? And that possibly their promise (of death) may have come near? So after this*, in what will they believe? (*Advent of the Last Prophet and the Holy Qur’an.) 185 No one can guide those whom God lets go astray: He leaves them blundering about in their arrogance. 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 Tell them: "I am not master of my own gain or loss but as God may please. If I had the knowledge of the Unknown I would have enjoyed abundance of the good, and no evil would have touched me. I am only a bearer of warnings and bringer of happy news for those who believe." 188
