“One who is not pious is not religious, and one who does not practice concealing faith does not have faith. The dearest one from among you near God is the one who practices concealing of faith the most.” Then the people asked the Prophet's descendent (a.s): “Until when should we continue to practice concealing of faith?” He replied: “Until a predetermined day, the day on which our Riser will rise. Whoever abandons concealing of faith before that day does not belong to our nation.” Then they asked: “O' descendent of the Prophet! From what family is your Riser?” He replied: “He is from my fourth generation, the son of the Lady of the Maids. Through him God will eliminate all oppression from the Earth.” This tradition has been narrated by Seyed al-Saeed Jalal al-Din Abu-Ali ibn Hamzeh al-Mousavi in his book on the authority of his teachers, on the authority of a trustworthy person, on the authority of the Prophet (a.s) and the Imams (a.s).
