He is only a plain admonisher. 184 Do they not consider the kingdom of the heavens and the earth and whatever things Allah has created, and that may be their doom shall have drawn nigh; what announcement would they then believe in after this? 185 None can guide those whom Allah leaves in error. He leaves them in their insolence, 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 autonomy to benefit or hurt myself, except what Allah wills; and were I to procure knowledge of the hidden on my own, it would be that I had accumulated a lot of good; and no misfortune would touch me; I am purely a Herald of Warning and Glad Tidings to the people who believe.” 188
