Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 Though I have given them a respite, My plan against them is well established. 183 Do they not ponder that their companion is far removed from insanity? In fact he is clearly a Herald of Warning. 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 thee about the (final) Hour - when will be its appointed time? Say: "The knowledge thereof is with my Lord (alone): None but He can reveal as to when it will occur. Heavy were its burden through the heavens and the earth. Only, all of a sudden will it come to you." They ask thee as if thou Wert eager in search thereof: Say: "The knowledge thereof is with Allah (alone), but most men know not." 187 Say, "I myself have no power to benefit or do harm, save as God pleases. If I had knowledge of the unseen, I would have availed myself of an abundance of good, and no harm would have touched me. I am but a warner and a bearer of good tidings for those who will believe." 188
