Those who reject Our signs, We shall gradually visit with punishment, in ways they perceive not; 182 And I will give them time. Indeed, my plan is firm. 183 Reflect they not that in their companion there is no madness! he is naught but a manifest warner. 184 Or have they not considered the dominion of the heaven and of the earth, and what things God has created, and that it may be their term is already nigh? In what manner of discourse then will they after this believe? 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 and when it is to come. Say: 'None knows except my Lord. He alone will reveal it at the appointed time. It is heavy in the heavens and earth. It will not come to you but suddenly' They will question you, as though you had full knowledge of it. Say: 'Its knowledge is with Allah, though most people are unaware' 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
