This mosque was built by the order of Imam Mahdi (a.j) on 17th Ramadan 293 A.H. His Excellency recommended his Shiites to come and pray in this mosque, and he has said: “whoever prays in this place, it is as if he has prayed in Ka’bah”. That’s why his countless needful lovers take refuge in this mosque and find the realization of their prayers under the attentions of His Excellency. The building of this mosque has been changing over the centuries, it is now considered one of the largest mosques of Iran in which the lovers of Imam Mahdi (a.j) pray for the advent of their dear one in occultation every week, and seek refuge in the owner of the sanctuary against seditions and chaos of end times. The sanctuary is located on the hillside of Dobaradaran Mount and the beginning of Qum-Kashan road.
