To the southeast of Tehran, just beyond that city's vast urban sprawl, lies the ancient city of Rey and its pilgrimage shrine of Shah-e' Abdal-Azim. Archaeological evidence indicates the city was important during the Achaemenian (559-330 BC) and Sassanian (224-637 AD) periods. Rey was occupied by the Muslims in 635 AD, was the regional capital in the 11th and 12th centuries, and was later plundered by rampaging Mongols in the 13th century. Within the large shrine complex are buried the religious scholar Shah Abdul Azim (786-865 AD), a descendant of Imam Hussein; Hamzeh, a brother of Imam Reza; Hussain, the great-grandson of the second Imam Hassan, and Taher, a descendant of the fourth Imam

Shah-Abdol-Azim shrine
The Shah Abdol Azim Shrine (Persian: شاه عبدالعظیم‎), located in Rey, Iran, contains the tomb of: ‘Abdul ‘Adhīm ibn ‘Abdillah al-Hasanī (aka. Shah Abdol Azim). Shah Abdol Azim was a fifth generation descendant of Hasan ibn ‘Alī and a companion of Muhammad al-Taqī. He was entombed here after his death in the 9th century.Adjacent to the shrine, within the complex, include the mausolea of Imamzadeh Tahir (son of the fourth shia Imam Sajjad), and Imamzadeh Hamzeh (brother of the eighth Twelver Imām - Imam Reza).Abdol Azim migrated to Rayy out of persecution and subsequently died there. A piece of paper was found in his pocket outlining his ancestry as being: ‘Abdul ‘Adhīm son of ‘Abdillāh son of ‘Alī son of Husayn son of Zayd son of Hasan ibn ‘Alī. Shah Abdol Azim was sent to Rayy ( Modern day Tehran) by Imam Reza. His journey was full of hardships but he successfully reached there and delivered the message of Imam. He was one of the pious persons of his time. During his journey many spies of Abbasid Caliph Al-Matawakkil tried to capture him but failed. A movie on the life of Shah Abdol Azim Al-Hasani has been made and is available in Persian and Urdu languages.
