Surah No. 4 187. They ask thee about the (final) Hour - when will be its appointed time? Say: The knowledge thereof is with my Lord (alone): None but He can reveal as to when it will occur. Heavy were its burden through the heavens and the earth. Only, all of a sudden will it come to you. They ask thee as if thou Wert eager in search thereof: Say: The knowledge thereof is with Allah (alone), but most men know not.
188. 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.
