ʿAbd-al-Mīṯāq Mīṯāqīya, ( 'Abdu'l-Missagh Missaghiyeh) a well-known Bahá'í of Tehran, built a hospital and donated it to the Bahá'í community. The hospital rapidly developed to employ highly respected physicians, and to obtain advanced equipment. It became known as one of the best medical centres in Tehran.
• In the early 1970s a nursing school, affiliated with the hospital, was inaugurated and the hospital itself opened medical clinics in Boir Aḥmad [BW16p264; BAHAISM v. The Bahai Community in Iran by V. Rafati]

He made a pilgrimage in 1912 and a second one in 1919. Upon his departure he was given a gold coin by 'Abdu'l-Bahá which he interpreted as a sign that he would have great wealth. In addition to the services he rendered as a member of Bahá'í institutions and through the teaching trips he made throughout lran offering encouragement to the friends, he made generous gifts of funds which made possible the acquisition of lands and buildings for the Faith in Asia, Europe and Africa. These gifts were made without ostentation, often without even his family being informed and in many cases in response to Shoghi Effendi's wishes. Although it is impossible to compile a complete record, his munificence can be glimpsed by mentioning that in Africa alone he had up to 1958 purchased no less than forty-four Temple sites, Teaching Institutes, Bahá'í Centres and other sites.

Another notable contribution was the Missaghiyeh Hospital and Maternity Clinic in Tehran.
