As for those who reject Our signs as false, We shall lead them, step by step, to their ruin without their even perceiving it. 182 and I respite them -- assuredly My guile is sure. 183 Have they not bethought themselves their companion is not mad? He is only a plain admonisher. 184 Have they not considered the dominion of the heavens and the earth, and what things Allah hath created, and that it may be that their own term draweth nigh? In what fact after this will they believe? 185 Whomsoever Allah sends astray, none can guide him; and He lets them wander blindly in their transgressions. 186 They will question thee concerning the Hour, when it shall berth. Say: 'The knowledge of it is only with my Lord; none shall reveal it at its proper time, but He. Heavy is it in the heavens and the earth; it will not come on you but suddenly!' They will question thee, as though thou art well-informed of it. Say: 'The knowledge of it is only with God, but most men know not.' 187 Tell them [O Muhammad]: 'I have no power to benefit or harm myself except as Allah may please. And had I knowledge of the unseen, I should have amassed all kinds of good, and no evil would have ever touched me. I am merely a warner and the herald of glad tidings to those who have faith.' 188
