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 (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 Have they, then, never considered [God's] mighty dominion over the heavens and the earth, and all the things that God has created, and [asked themselves] whether, perchance, the end of their own term might already have drawn nigh? In what other tiding, then, will they, after this, believe? 185 To such as Allah rejects from His guidance, there can be no guide: He will leave them in their trespasses, wandering in distraction. 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 myself have no power to benefit or do harm, save as God pleases. If I had knowledge of the unseen, I would have availed myself of an abundance of good, and no harm would have touched me. I am but a warner and a bearer of good tidings for those who will believe." 188
