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; certainly My Plan is strong. 183 Do they not reflect that their companion has not unsoundness in mind; he is only a plain warner. 184 Do they not consider the kingdom of the heavens and the earth and whatever things Allah has created, and that may be their doom shall have drawn nigh; what announcement would they then believe in after this? 185 For one whom Allah sends astray, there is none to guide him; and He leaves them to wander in their rebellion. 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
