As for those who reject Our signs as false, We shall lead them, step by step, to their ruin without their even perceiving it. 182 And I give them rein: verily My contrivance is firm. 183 Have they not reflected? There is no madness in their companion, he is but a plain 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 Those whom Allah sendeth astray, there is no guide for them. He leaveth them to wander blindly on in their contumacy. 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: "I have no power over any good or harm to myself except as Allah willeth. If I had knowledge of the unseen, I should have multiplied all good, and no evil should have touched me: I am but a warner, and a bringer of glad tidings to those who have faith." 188
