Mukhtasar Bukhari

Narrated Abu Huraira (may Allah be pleased with him): The Messenger of Allah (peace and blessings of Allah be upon him) said: "When the Hour draws near, the dream of a believer will not be false (rather, it will be absolutely true), and the dream of a believer is one part out of forty-six parts of Prophethood, and whatever is from Prophethood can never be false."
