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 Do they not reflect? Their companion is not seized with madness: he is but a perspicuous warner. 184 Have they, then, never considered [God's] mighty dominion over the heavens and the earth, and all the things that God has created, and [asked themselves] whether, perchance, the end of their own term might already have drawn nigh? In what other tiding, then, will they, after this, believe? 185 Whosoever God allows to go astray has none to show him the way, for He leaves them to wander perplexed in their wickedness. 186 They ask you about the hour, when will be its taking place? Say: The knowledge of it is only with my Lord; none but He shall manifest it at its time; it will be momentous in the heavens and the earth; it will not come on you but of a sudden. They ask you as if you were solicitous about it. Say: Its knowledge is only with Allah, but 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
