Those who reject Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), We shall gradually seize them with punishment in ways they perceive not. 182 I will just give them respite. My plan is certainly invincible. 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 184 Have they not considered the dominion of the heavens and the earth, and what things Allah hath created, and that it may be that their own term draweth nigh? In what fact after this will they believe? 185 Those whom Allah sendeth astray, there is no guide for them. He leaveth them to wander blindly on in their contumacy. 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: For myself I have no power to benefit, nor power to hurt, save that which Allah willeth. Had I knowledge of the Unseen, I should have abundance of wealth, and adversity would not touch me. I am but a warner, and a bearer of good tidings unto folk who believe. 188
