Their destruction will be such that they will not even notice how it seized them. 182 And I respite them; certainly My Plan is strong. 183 Do they not ponder that their companion is far removed from insanity? In fact he is clearly a Herald of Warning. 184 Have they not observed the kingdom of the heavens and the earth, and all that Allah has created and that their term of life might have drawn near After this warning from the Prophet, what will it be that will make them believe? 185 For those whom Allah lets go astray, there is no guide; and He will leave them in their transgression to stumble blindly. 186 They ask you, [O Muhammad], about the Hour: when is its arrival? Say, "Its knowledge is only with my Lord. None will reveal its time except Him. It lays heavily upon the heavens and the earth. It will not come upon you except unexpectedly." They ask you as if you are familiar with it. Say, "Its knowledge is only with Allah, but most of the 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
