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 Look they not at the governance of the heaven and the earth and whatsoever Allah hath created of aught, and at the fact that their term may have drawn nigh? In what discourse then will they, thereafter, believe! 185 Whomsoever Allah sends astray, none can guide him; and He lets them wander blindly in their transgressions. 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
