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 will give them time. Indeed, my plan is firm. 183 Do they not ponder that their companion is far removed from insanity? In fact he is clearly a Herald of Warning. 184 Do they not look into the realm of the heavens and the earth and everything that Allah has created and [think] that perhaps their appointed time has come near? So in what statement hereafter will they believe? 185 Whomsoever Allah sends astray, none can guide him; and He lets them wander blindly in their transgressions. 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 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
