We gradually lead those who have called Our revelations mere lies, to destruction. Their destruction will be such that they will not even notice how it seized them. 182 I give them rein (for) lo! My scheme is strong. 183 Have they not reflected? No madness is in their comrade; he is naught but a plain warner. 184 Have they not observed the kingdom of the heavens and the earth, and all that Allah has created and that their term of life might have drawn near After this warning from the Prophet, what will it be that will make them believe? 185 For those whom God lets go astray, there is no guide; and He shall leave them in their overweening arrogance, blindly stumbling to and fro. 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 do not control any benefit or harm for my own soul except as Allah please; and had I known the unseen I would have had much of good and no evil would have touched me; I am nothing but a warner and the giver of good news to a people who believe. 188
