Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 And (for this purpose) I will grant them respite. My design is incontrovertible. 183 Have they not bethought themselves their companion is not mad? He is only a plain admonisher. 184 Have they not contemplated the kingdom of the heavens and the earth and everything created by God, (to educe) that perhaps their own term is drawing to a close? In what lore after this would they then believe? 185 Whomsoever Allah sends astray, none can guide him; and He lets them wander blindly in their transgressions. 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 power over any good or harm to myself except as Allah willeth. If I had knowledge of the unseen, I should have multiplied all good, and no evil should have touched me: I am but a warner, and a bringer of glad tidings to those who have faith." 188
