In the name of Allah, most Gracious, most Merciful.
186. To such as Allah rejects from God's Guidance, there can be no guide. God will leave them in their trespasses, wandering in distraction.
187. They ask you about the Hour: when will be its appointed time? Say, "The knowledge thereof is with my Lord. None can reveal as to when it will occur. Heavy is its burden through the heavens and the earth. Only all of a sudden will it come to you." They ask you if you were eager in search thereof. Say, "The knowledge thereof is with Allah, but most humans know not."
188. Say, "I have no power over any good or harm to myself except as Allah Wills. 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."
