Abd al-Azim al-Hasani was born on Thursday, the 4th of Rabi' al-Thani 173 AH (13 September 789 CE), during the time of the seventh Shia Imam,
Musa al-Kazim, in
Medina. His father’s name was Abdullah and his mother’s name was Fatimah. His wife was Khadijah, the daughter of Qasim ibn Hasan ibn Zayd ibn Hasan al-Mujtaba (his paternal cousin), who is buried in
Tehran, Iran, at Imamzadeh Qasem. Abd al-Azim entered the city of Rey by the order of the Eighth Shia Imam,
Reza, and lived in concealment in the basement of a Shia resident’s house. He fasted during the days and stood in prayer at night. Occasionally, he would secretly leave the house to visit a grave that is now located opposite his own shrine. After some time, he fell ill and passed away on Tuesday, the 15th of Shawwal 252 AH (11 November 866 CE), during the time of Imam al-Hadi and under the Abbasid Caliphate. He lived for 79 lunar years (77 solar years). == Burial ==
