And those who deny Our revelations - step by step We lead them on from whence they know not. 182 and I respite them, My stratagem is firm. 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 not consider the kingdom of the heavens and the earth and whatever things Allah has created, and that may be their doom shall have drawn nigh; what announcement would they then believe in after this? 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 you (Muhammad), "When will the Day of Judgment be?" Tell them, "My Lord knows best. It is He who has appointed its time. It will be a grave hour both in the heavens and the earth. It will only approach you suddenly." They say, "It seems that you know about the coming of the Day of Judgment." Tell them, "Only God knows about it and most people do not know." 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
