Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 and I respite them -- assuredly My guile is sure. 183 Reflect they not that in their companion there is no madness! he is naught but a manifest warner. 184 Do they not look in the dominion of the heavens and the earth and all things that Allah has created, and that it may be that the end of their lives is near. In what message after this will they then believe? 185 Whosoever God allows to go astray has none to show him the way, for He leaves them to wander perplexed in their wickedness. 186 They will question thee concerning the Hour, when it shall berth. Say: 'The knowledge of it is only with my Lord; none shall reveal it at its proper time, but He. Heavy is it in the heavens and the earth; it will not come on you but suddenly!' They will question thee, as though thou art well-informed of it. Say: 'The knowledge of it is only with God, but most men 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
