There are numerous Hadith (prophetic sayings) cited in Sunni and Shia sources from Prophet Muhammad (PBUH) and his descendants (Ahl Al-Bayt) concerning the appearance of Imam Mahdi (PBUH), such as that he is of the progeny of the Prophet (PBUH) and that his appearance will enable human society to reach true perfection and the full realization of spiritual life. In addition, there are numerous other traditions concerning the fact that Imam Mahdi (PBUH) is the son of the eleventh descendant of Prophet Muhammad (PBUH), Imam Hassan Askari (PBUH).
