Imamzadeh Saleh, which is known as one of the children of Imam Musa Kazem (AS), is one of the cultural, pilgrimage and tourism centers in the north of Tehran, which, according to the Imamzadegan Jame base, has about 30,000 pilgrims daily. Due to the location of the shrine in the central area of Tajrish and the frequent movement of people and pilgrims, the market of Tajrish was gradually formed.

In the past, the courtyard and yard of Imamzadeh Saleh mausoleum was the burial place of the dead and there were graves in its courtyard, but gradually the tombstones disappeared and only a small number of tombstones remained. Iran's nuclear martyrs are among the famous people buried in the shrine.

The documentary film "Saleh Shemiran" narrates the biography of the brother of Imam Reza (AS) and the history of Imamzadeh Saleh shrine. This movie was directed and produced by Babak Minaei and narrated by Parviz Bahram in 2015 and then broadcasted on the Islamic Republic of Iran.

The 5th of Dhul-Qa'dah, which is between the births of Hazrat Masoumeh (pbuh) and Imam Reza (pbuh), is named after Saleh bin Musa Al-Kazim (pbuh).
