We shall punish those who deny Our revelations slowly in a way that they will not know. 182 I give them rein (for) lo! My scheme 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 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 For those whom God lets go astray, there is no guide; and He shall leave them in their overweening arrogance, blindly stumbling to and fro. 186 They ask thee of the (destined) Hour, when will it come to port. Say: Knowledge thereof is with my Lord only. He alone will manifest it at its proper time. It is heavy in the heavens and the earth. It cometh not to you save unawares. They question thee as if thou couldst be well informed thereof. Say: Knowledge thereof is with Allah only, but most of mankind know not. 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
