But as for those who are bent on giving the lie to Our messages - We shall bring them low, step by step, without their perceiving how it came about: 182 and I respite them -- assuredly My guile is sure. 183 Do they not reflect? Their companion is not seized with madness: he is but a perspicuous 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 None can guide those whom Allah leaves in error. He leaves them in their insolence, wandering blindly. 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 Say thou: I possess no power over benefit or hurt to myself save as Allah willeth; and had I knowledge of the unseen I would have amassed ample good, and evil would not have touched me. I am naught but a warner and a bringer of tidings unto a people who believe. 188
