"Qom Hawza (Persian: \u062D\u0648\u0632\u0647 \u0642\u0645\u200E\u200E) is largest Hawza (seminary of traditional Islamic school of higher learning.) established in 1922 by Grand Ayatollah Abdul-Karim Ha'eri Yazdi in Qom.Although big Shi'a academies existed in Qom dating back as early as 10th century CE, the hawza of the city became prominent at the time of the Safavids when Shi'a Islam became the official religion of Iran. The famous teachers of that era included Mulla Sadra and Shaykh Bahai."@en .
