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 give them rein: verily My contrivance is firm. 183 Reflect they not that in their companion there is no madness! he is naught but a manifest warner. 184 Have they not pondered deeply regarding the kingdom of the heavens and the earth, and whatever things Allah created? And that possibly their promise (of death) may have come near? So after this*, in what will they believe? (*Advent of the Last Prophet and the Holy Qur’an.) 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 you about the Hour: "When is its determined time?" Say: "Only my Lord has the knowledge. No one can reveal it except He. Oppressive will it be for the heavens and the earth. When it comes, it will come unawares." They ask you about it as if you were in the know. You tell them: "Only God has the knowledge." But most people do not know. 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
