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 grant them respite; surely My scheme is effective. 183 Has it, then, never occurred to them that there is no madness whatever in [this] their fellowman? He is only a plain 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 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 thee concerning the Hour, when will its coming be? Say thou: knowledge thereof is with my Lord only: none shall disclose it at its time but He; heavy it is in the heavens and the earth; it shall not come upon you except on a sudden. They ask thee as though thou wert familiar therewith. Say thou: knowledge thereof is with Allah only; but most of men know not. 187 Say, "I hold not for myself [the power of] benefit or harm, except what Allah has willed. And if I knew the unseen, I could have acquired much wealth, and no harm would have touched me. I am not except a warner and a bringer of good tidings to a people who believe." 188
