But those who deny Our signs - We will progressively lead them [to destruction] from where they do not know. 182 And (for this purpose) I will grant them respite. My design is incontrovertible. 183 Have they not reflected? There is no madness in their companion, he is but a plain warner. 184 Do they not look in the dominion of the heavens and the earth and all things that Allah has created, and that it may be that the end of their lives is near. In what message after this will they then believe? 185 Whomsoever God leads astray, no guide he has; He leaves them in their insolence blindly wandering. 186 They ask thee of the (destined) Hour, when will it come to port. Say: Knowledge thereof is with my Lord only. He alone will manifest it at its proper time. It is heavy in the heavens and the earth. It cometh not to you save unawares. They question thee as if thou couldst be well informed thereof. Say: Knowledge thereof is with Allah only, but most of mankind know not. 187 Say [O Prophet]: "It is not within my power to bring benefit to, or avert harm from, myself, except as God may please. And if I knew that which is beyond the reach of human perception, abundant good fortune - would surely have fallen to my lot, and no evil would ever have touched me. I am nothing but a warner, and a herald of glad tidings unto people who will believe." 188
