Takyeh

Shia Muslims gather to mourn the death of Husayn ibn Ali in the month of Muharram),^[2][3][4] although some takyehs also include a zaynabiyya (or zeynabiyeh, in honor of Husayn's sister Zaynab bint Ali)^[5] or an abbasiyya (or abbasiyeh, in honor of Husayn's paternal half-brother Abbas ibn Ali), like the Takyeh Moaven-ol-Molk.^[6] Many takyehs are found in Iran,^[7] where there are takyehs in almost every city.^{[citation needed}

Sufi gatherings; Sufis were called تکیه‌نشین takya-nishīn or تکیه‌دار takya-dār. Following the Safavid conversion of Iran to Shia Islam, existing takyas became used as husayniyyas,^[8] and the majority of takyehs built in Iran since Iran's conversion have been built to be used as husayniyyas, like the Takyeh Dowlat built by Naser al-Din Shah Qajar. Tehran alone is said to have had up to 50 takyehs under the Qajar dynasty.^[3]
