this is from a brailvi website
We find in a narration from the collection of Imam Bukhari :
Prophet Muhammad (May Allah bless him and grant him peace) stood up in one meeting and he started to tell us about events from the beginning of this world to the end and he told us about heaven and hell and about the people who were going to hell and who were going to heaven and what will be their places in heaven and hell. Of course, some people remember what he told us and some people have forgotten.
(Bukhari, Chapter Bada-Ul-Khalq.)
if this is not evrything then what is , this is ilm e ghayb the future is ilm eghayb.
