Abu’l Hijaf narrates that our Prophet (saas) said the following three times: “Let there be glad tidings for you regarding Hazrat Mahdi (as). HE WILL APPEAR WHEN THE PEOPLE ARE DISPERSED AND TROUBLES ARISE. HE WILL FILL THE WORLD THAT IS FULL OF OPPRESSION AND LAMENTATION WITH JUSTICE INSTEAD. HE WILL INSTALL SERVITUDE TO ALLAH IN THE HEARTS OF HIS SERVANTS AND HIS JUSTICE WILL ENFOLD ALL PLACES.
(Hazrat Mahdi (as) from the ahl al-bayt of our Prophet (saas), p. 16;
Bihar al-Anwar, vol.51, p.74)
The hadith reports that Hazrat Mahdi (as) will appear when there are sectarian differences, when people form groups and turn away from one another, when there is racial sectarianism, when there are economic problems and when there is an increase in terror and anarchy. Our Prophet (saas) repeated this hadith three times. He also stated that this time would be one of economic crisis, in which people constantly complained of high prices and the material and spiritual troubles afflicting them and the oppression they were subjected to.
