When corruption and enmity enfold the world, when everywhere is filled with oppression, strife and looting, THEN ALLAH WILL SEND HIS GREAT REFORMER TO TEAR DOWN THE BASTIONS OF DEPRAVITY AND DISTRACTION FROM THE TRUE PATH AND TO LIGHT THE DARKNESS AND STONY HEARTS WITH MONOTHEISTIC BELIEF (BELIEF IN THE ONENESS OF ALLAH), HUMANITY AND JUSTICE.
(Al-Mahdi al-Mawud, Vol. 1, p. 310)
