Those who reject Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), We shall gradually seize them with punishment in ways they perceive not. 182 And I will give them time. Indeed, my plan is firm. 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 None can guide those whom Allah leaves in error. He leaves them in their insolence, wandering blindly. 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 Say (O Muhammad SAW): "I possess no power of benefit or hurt to myself except as Allah wills. If I had the knowledge of the Ghaib (unseen), I should have secured for myself an abundance of wealth, and no evil should have touched me. I am but a warner, and a bringer of glad tidings unto people who believe." 188
