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 -- assuredly My guile is sure. 183 Reflect they not that in their companion there is no madness! he is naught but a manifest 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 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 about the (final) Hour - when will be its appointed time? Say: "The knowledge thereof is with my Lord (alone): None but He can reveal as to when it will occur. Heavy were its burden through the heavens and the earth. Only, all of a sudden will it come to you." They ask thee as if thou Wert eager in search thereof: Say: "The knowledge thereof is with Allah (alone), but most men know not." 187 Tell them [O Muhammad]: 'I have no power to benefit or harm myself except as Allah may please. And had I knowledge of the unseen, I should have amassed all kinds of good, and no evil would have ever touched me. I am merely a warner and the herald of glad tidings to those who have faith.' 188
