Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 and I respite them -- assuredly My guile is sure. 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 pondered deeply regarding the kingdom of the heavens and the earth, and whatever things Allah created? And that possibly their promise (of death) may have come near? So after this*, in what will they believe? (*Advent of the Last Prophet and the Holy Qur’an.) 185 None can guide those whom Allah leaves in error. He leaves them in their insolence, wandering 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 Say: 'I do not have the power to acquire benefits or to avert harm from myself, except by the Will of Allah. Had I possessed knowledge of the unseen, I would have availed myself of much that is good, and no harm would have touched me. But I am only a warner and a bearer of glad tidings for a nation who believe. 188
