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 Have they not reflected? No madness is in their comrade; he is naught but a plain 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 Whomsoever God leads astray, no guide he has; He leaves them in their insolence blindly wandering. 186 They ask you about the Hour: "When is its determined time?" Say: "Only my Lord has the knowledge. No one can reveal it except He. Oppressive will it be for the heavens and the earth. When it comes, it will come unawares." They ask you about it as if you were in the know. You tell them: "Only God has the knowledge." But most people do not know. 187 Say, "I hold not for myself [the power of] benefit or harm, except what Allah has willed. And if I knew the unseen, I could have acquired much wealth, and no harm would have touched me. I am not except a warner and a bringer of good tidings to a people who believe." 188
