The Holy Prophet Muhammad(SAW) has prophesied about several events that will occur just before the advent of the day of judgment.  Among these, Rasulullah has foretold the advent of one of his descendants, Al Mahdi (the guided one), which will materialize when the believers are severely oppressed in every corner of the world.  He will fight the oppressors, unite the Muslims, bring peace and justice to the world, rule over the Arabs, and lead a prayer in Mekkah at which Isa(pbuh) (Jesus) will be present.
