In fact he is clearly a Herald of Warning. 184 Have they not looked into the realms of the heavens and the earth and all that God created, and seen that the end of their time might be near? What will they believe in if they do not believe in this? 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 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
