We shall punish those who deny Our revelations slowly in a way that they will not know. 182 And I give them rein: verily My contrivance is firm. 183 Have they not reflected that their companion is not mad? He is only a plain 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 Allah causes to err, there is no guide for him; and He leaves them alone in their inordinacy, blindly wandering on. 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 hold not for myself [the power of] benefit or harm, except what Allah has willed. And if I knew the unseen, I could have acquired much wealth, and no harm would have touched me. I am not except a warner and a bringer of good tidings to a people who believe." 188
