It was narrated that Abu Hurairah said:
“I heard the Messenger of
Allah (ﷺ) say: ‘The Hour will not begin until the sun rises from
the
west (i.e. the place of its setting). When it rises, the people
will
see it, and everyone on (earth) will believe, but that will be
at a
time when faith will not benefit anyone who did not believe
before.’”
