And (as to) those who reject Our communications, We draw them near (to destruction) by degrees from whence they know not. 182 And I grant them respite; surely My scheme is effective. 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 184 Do they see nothing in the government of the heavens and the earth and all that Allah hath created? (Do they not see) that it may well be that their terms is nigh drawing to an end? In what message after this will they then believe? 185 Whomsoever Allah sends astray, none can guide him; and He lets them wander blindly in their transgressions. 186 They ask you about the Hour and when it is to come. Say: 'None knows except my Lord. He alone will reveal it at the appointed time. It is heavy in the heavens and earth. It will not come to you but suddenly' They will question you, as though you had full knowledge of it. Say: 'Its knowledge is with Allah, though most people are unaware' 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
