In the early 1960s, Saleh Ali-Shah, the former spiritual leader of the Gonabadi Dervish Order, endowed a large lot of land and then built a hospital at his own and a group of Gonabadi Dervishes’ expense there. The management of the hospital was later given to the Ministry of Health and Welfare (currently is called the Ministry of Health and Medical Education). After the 1979 revolution, the name of the hospital from Salehiyeh was changed to Panzdah-e Khordad, which refers to a massive demonstration in May 1963 that led to sending Ayatollah Khomeini to exile in Iraq. Gonabadi Dervishes were not in favor of such change.
On April 5, 2017, dozens of locals and Gonabadi Dervishes gathered in front of Panzdah-e Khordad Hospital protesting the plan of the Ministry of Health and Medical Education to close and divert the endowed property to another purpose. Some reports indicate that the hospital has been closed afterward. In February 2021, however, Panzdah-e Khordad Hospital in the city of Bidokht was reopened after renovation.
