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 And I grant them respite; surely My scheme is effective. 183 Do they not reflect? Their companion is not seized with madness: he is but a perspicuous warner. 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 For those whom Allah lets go astray, there is no guide; and He will leave them in their transgression to stumble blindly. 186 They ask you [Prophet] about the Last Hour, "When will it come?" Say, "Knowledge about it rests only with my Lord; He alone will reveal when its time will come, it lies heavy on the heavens and the earth: it will suddenly overtake you." They will put questions to you as though you had full knowledge of it. Say, "Knowledge about it rests only with God, though most people do not realize it." 187 (Muhammad), say, "I have no control over my benefits or sufferings, without the will of God. Had I known about the unseen, I would have gained much good and would have faced no suffering. I am only a warner and I preach the glad news to the believing people." 188
