Our Prophet's (saas) addresses to Hazrat Mahdi (as)

Hazrat Mahdi (as) is the peacock (adornment) of the Paradise. (Bihar al-Anwar, Vol 51, p. 105)

Hazrat Mahdi (as), one of my children, comes into being, by the blessing of Allah, upon the approach of the Day of Judgment; the weakening of the believers' hearts because of death, hunger, fitnah and the disappearance of the Sunnah; and the emergence of innovations and the loss of means by which to enjoin the right and forbid the wrong. His justice and prosperity will ease the believers' hearts, and friendship and love will settle between the non-Arab and the Arab nations. (Al-Muttaqi al-Hindi, Al-Burhan fi Alamat al-Mahdi Akhir az-Zaman, p. 66)

Imam Hussain (as) is reported as saying: “When Hazrat Mahdi (as) appears, people will not recognize him. Then HE [HAZRAT MAHDI (AS)] WILL COME HAVING A BEAUTIFUL VISAGE...” (Iqdud Durar, p. 41)

A MAN CALLED AL-HARITH IBN HARRATH (LION) WILL COME FORTH FROM MA WARA AN-NAHR (TRANSOXIANA). His army will be led by a man called Mansur who will establish or consolidate things for Muhammad's family as Quraysh consolidated them for the Messenger of Allah (saas). Every believer must help him. (Sunan Abu Dawud, Book 36, 4277; Narrated Ali ibn AbuTalib; At-Taj al-jami' lil 'usul fi ahadith al-Rasul, Mansur 'Ali Nasif, Vol. 5, p. 617)
