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 give them rein: verily My contrivance is firm. 183 Have they not bethought them (that) there is no madness in their comrade? He is but a plain warner. 184 Do they not look into the realm of the heavens and the earth and everything that Allah has created and [think] that perhaps their appointed time has come near? So in what statement hereafter will they believe? 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 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: 'I have no power to profit for myself; or hurt, but as God will. Had I knowledge of the Unseen I would have acquired much good, and evil would not have touched me. I am only a warner, and a bearer of good tidings, to a people believing.' 188
