We gradually lead those who have called Our revelations mere lies, to destruction. Their destruction will be such that they will not even notice how it seized them. 182 and I respite them -- assuredly My guile is sure. 183 Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner. 184 Do they not look in the dominion of the heavens and the earth and all things that Allah has created, and that it may be that the end of their lives is near. In what message after this will they then believe? 185 None can guide those whom Allah leaves in error. He leaves them in their insolence, wandering blindly. 186 They ask you [Prophet] about the Last Hour, "When will it come?" Say, "Knowledge about it rests only with my Lord; He alone will reveal when its time will come, it lies heavy on the heavens and the earth: it will suddenly overtake you." They will put questions to you as though you had full knowledge of it. Say, "Knowledge about it rests only with God, though most people do not realize it." 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
