Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 And I will give them time. Indeed, my plan is firm. 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 observed the kingdom of the heavens and the earth, and all that Allah has created and that their term of life might have drawn near After this warning from the Prophet, what will it be that will make them believe? 185 Whomsoever Allah causes to err, there is no guide for him; and He leaves them alone in their inordinacy, blindly wandering on. 186 They ask thee concerning the Hour, when will its coming be? Say thou: knowledge thereof is with my Lord only: none shall disclose it at its time but He; heavy it is in the heavens and the earth; it shall not come upon you except on a sudden. They ask thee as though thou wert familiar therewith. Say thou: knowledge thereof is with Allah only; but most of men know not. 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
