Tradition
Ameerul Momineen (a.s.) recounts on the authority of the Holy Prophet (s.a.w.s.), ‘Even if there is only day left on this earth (before it ends), Allah will manifest a person from my progeny, who shall fill the earth with justice as it would have been wrecked with injustice and despotism.’
