And those who belie Our signs, step by step We lead them on in a way they know not. 182 And I give them rein: verily My contrivance is firm. 183 Have they not reflected that their companion is not mad? He is only a plain warner. 184 Will they not ponder upon the kingdom of the heavens and the earth, and all that Allah created, and that it may be that their term is drawing near? So, in which speech will they believe thereafter? 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 concerning the Hour, when will its coming be? Say: 'The knowledge of it is with my Lord alone: none but He will disclose it at its time. That will weigh heavily on the heavens and the earth; and it shall not come to you other than all of a sudden.' They ask you - as if you are eagerly inquisitive about it - concerning it. Say to them: 'The knowledge of it is with none except Allah. But most people are unaware of this reality.' 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
