And (as to) those who reject Our communications, We draw them near (to destruction) by degrees from whence they know not. 182 Respite will I grant unto them: for My scheme is strong (and unfailing). 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 184 Have they, then, never considered [God's] mighty dominion over the heavens and the earth, and all the things that God has created, and [asked themselves] whether, perchance, the end of their own term might already have drawn nigh? In what other tiding, then, will they, after this, believe? 185 No one can guide those whom God has caused to go astray and has left to continue blindly in their rebellion. 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
