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 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 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 causes to err, there is no guide for him; and He leaves them alone in their inordinacy, blindly wandering on. 186 They ask you (Muhammad), "When will the Day of Judgment be?" Tell them, "My Lord knows best. It is He who has appointed its time. It will be a grave hour both in the heavens and the earth. It will only approach you suddenly." They say, "It seems that you know about the coming of the Day of Judgment." Tell them, "Only God knows about it and most people do not know." 187 Say thou: I possess no power over benefit or hurt to myself save as Allah willeth; and had I knowledge of the unseen I would have amassed ample good, and evil would not have touched me. I am naught but a warner and a bringer of tidings unto a people who believe. 188
