My plan is certainly invincible. 183 Have they not bethought them (that) there is no madness in their comrade? He is but 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 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 to profit for myself; or hurt, but as God will. Had I knowledge of the Unseen I would have acquired much good, and evil would not have touched me. I am only a warner, and a bearer of good tidings, to a people believing.' 188
