Their most common practice is Sama which is associated with Rumi.  - Baku is the capital and largest city of Azerbaijan, as well as the largest city on the Caspian Sea and of the Caucasus region. Baku is located below sea level, which makes it the lowest lying national capital in the world and also the largest city in the world located below sea level. It is located on the southern shore of the Absheron Peninsula, alongside the Bay of Baku. At the beginning of 2009, Baku's urban population was estimated at just over two million people.

The inscription plaque over the portal , read by V. Kratchkovskaya in 1952 , announces that the khanqah ( dervish monastery ) was built by Sharaf al - Dawla wal - din Hasan during the reign of the Shirvanshah Afridhun Abul - Muzaffar Fariburz ( Fariburz III , 1225 - 1255 ) . The title gives a later date : `` Here lies the sheikh , imam , mystic ... Al - Husain , son of ' Ali , known as Pir Husain Rawanan ... His tomb was rebuilt by ' Umar , son of Muhammad al - Shirzadi of Qazvin and completed in the year of 684 ( 1280 B.C.E. ) . '' It is likely that the tomb of Pir Husayn bin Ali , an Azeri sheikh of the Qalandari sect who lived in the 11th century , existed on this site before a formal khanqah was built around it in the 13th century . Built out of cut - stone , the roughly rectangular complex was centered on an open courtyard fortified with ramparts , similar to a ribat . The crenellated rampart walls were buttressed with round bastions at the corners and semi-circular bastions at the middle of the south , east and west walls . A monumental gate centered on the eastern wall gave access to the courtyard , which was surrounded with halls of different sizes to its north and west , including a mosque on the western wing and a single minaret near the northeastern corner . The Pir Husayn Khanqah was renowned for the glazed tiles covering the interior of the tomb and the sheikh 's sarcophagus , which had disappeared entirely by 1913 . By the 1940s , more than four hundred of the tomb 's cross and star - shaped tiles were identified by V. Kratchkovskaya at the Hermitage Museum ( St. Petersburg ) and the State Museum of Georgia ( Tbilisi ) , including tiles from the inscriptive frieze of the mausoleum .
