And those who belie Our signs, step by step We lead them on in a way they know not. 182 And (for this purpose) I will grant them respite. My design is incontrovertible. 183 Why will they not understand that their companion (Muhammad) is not possessed by jinn. (Muhammad) is only a (Divinely) authorized preacher. 184 Have they not looked into the realms of the heavens and the earth and all that God created, and seen that the end of their time might be near? What will they believe in if they do not believe in this? 185 No one can guide those whom God lets go astray: He leaves them blundering about in their arrogance. 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 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
