Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 And I will give them time. Indeed, my plan is firm. 183 Reflect they not that in their companion there is no madness! he is naught but a manifest 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 Whomsoever God leads astray, no guide he has; He leaves them in their insolence blindly wandering. 186 They will question thee concerning the Hour, when it shall berth. Say: 'The knowledge of it is only with my Lord; none shall reveal it at its proper time, but He. Heavy is it in the heavens and the earth; it will not come on you but suddenly!' They will question thee, as though thou art well-informed of it. Say: 'The knowledge of it is only with God, but most men know not.' 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
