We shall punish those who deny Our revelations slowly in a way that they will not know. 182 And I respite them; certainly My Plan is strong. 183 Have they not pondered that their companion [i.e. the Prophet Muhammad] is not afflicted with insanity? He is only 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 Those whom Allah sendeth astray, there is no guide for them. He leaveth them to wander blindly on in their contumacy. 186 THEY WILL ASK thee [O Prophet] about the Last Hour: "When will it come to pass?" Say: "Verily, knowledge thereof rests with my Sustainer alone. None but He will reveal it in its time. Heavily will it weigh on the heavens and the earth; [and] it will not fall upon you otherwise than of a sudden." They will ask thee - as if thou couldst gain insight into this [mystery] by dint of persistent inquiry! Say: "Knowledge thereof rests with my Sustainer alone; but [of this] most people are unaware." 187 Say: 'I have no power to profit for myself; or hurt, but as God will. Had I knowledge of the Unseen I would have acquired much good, and evil would not have touched me. I am only a warner, and a bearer of good tidings, to a people believing.' 188
