Ṭūs (Persian: طوس), also spelled as Tous and Toos, is an ancient city in Khorasan, which is located near Mashhad, the current capital city of Razavi Khorasan province, northeast of Iran. Tus was founded in Sassanid era before the emergence of Islam in this country. It was a thriving city before the conquest of Khorasan by Muslims. It consisted of four major cities, Taberan, Noqan, Torqbaz and Radkan.
Harun, the Abbasid caliph, died in Tus and he was buried in Sanabad, a village near this city. On his way back from Marv, Imam al-Rida (a) was martyred and he was buried in Sanabad. Imam (a) also added two verses to a poem composed by Di'bil b. 'Ali al-Khuza'i in which he mentioned he will be buried in Tus.
This city was hugely damaged in the attacks of Mongols and Timurids in which a large number of people were perished. Then most of people moved to live in Sanabad where Imam al-Rida (a) was buried. These events led to marginalization of Tus. However Mashhad became increasingly famous and it became an important Shi'ite city.
The ancient city of Tus is currently located 25 km on the northern part of Mashhad.
Some historians believe the origin of Tus goes back to Achaemenid era and it was called Susia at that time. However, Tus is not mentioned in any historical resources until Sassanid era. It was among the most flourishing cities of Iran in Sassanid era. According to a number of reports, Jamshid Pishdadi founded this city and Tus b. Nowdar rebuilt it later.
After the Emergence of Islam
After the emergence of Islam in Khorasan, Tus was conquered by 'Abd Allah b. Kurayz in 29/649-650. In the early centuries after the emergence of Islam, Tus consisted of four parts (cities) Taberan, Noqan, Torqbaz and Radkan. Noqan was the most important and the largest city in Tus region in the 3rd/9th century.
Humayd b. Qahtaba al-Ta'i was the governor of Tus in the time of Abbasid caliphs, Harun and Ma'mun; he was living in a magnificent palace in Sanabad. When Harun traveled to Tus in order to suppress rioters in Khorasan, he became sick and died in Tus in 193/809. His body was buried in the garden of Humayd b. Qahtaba which later became famous as Haruniyya cemetery.
According to the reports of Muslim scholars in geography and history from the 3rd/9th century to the 9th/15th century after Hijra, including al-Ya'qubi, Istakhri, Ibn Hawqal, Ibn Khallakan, al-Maqdasi, Hirawi and al-Mustawfi, Tus was a prosperous and flourishing city which included more than a thousand villages. However after the attacks of Ghaznavids, Mongols and Timurids through three centuries (6th/12th - 9th/15th), Tus was demolished and abandoned. Later Shahrukh the son of Timur ordered to rebuild Tus after the damages caused by Timurids; it never became an elegant city as before though.
Most of the people who abandoned Tus, settled in Sanabad and started to build houses near the burial place of Imam al-Rida (a). Gradually Mashhad expanded and developed, meanwhile economic, political and social position of Tus moved to Mashhad. Timurids paid huge attention to the Holy Shrine of Imam al-Rida (a) and they built Goharshad mosque near it. Later Shi'ism was declared as the official religion in Iran by Safavid rulers which helped Mashhad to become one of the main Shi'ite cities in Iran. As a result, gradually from the 9th/15th century Tus was eliminated from historical geography and it was replaced with Mashhad.

After the martyrdom of Imam al-Rida (a) in Marv, on his way back to Iraq in 203/818, his body was buried in the garden of Humayd b. Qahtaba near Sanabad village by the order of Ma'mun. In the beginning there was only a burial place built on the grave of Harun, but later in the last decades of the 3rd/9th century people started to build houses there, which connected Sanabad village to Noqan, it was later called Mashhad al-Rida.

- Until the Resurrection, when Allah sends the Riser
- who will relieve us from the distresses and grief."
