Sadr al-Din al-Khiyawi (d. 860/1455), a Khalwati shaykh attributed to Khiyav in southern Azerbaijan, was the successor of Hajji Izz al-Din al-Turkmani and guided disciples in Shamakhi, the capital of Shirvan. His foremost disciple was Sayyid Yahya al-Shirvani, the order's second pir; after the succession dispute that followed his death, Yahya moved to Baku. As his grave is not firmly documented, no coordinates are given. (Sources: TDV 'Khalwatiyya'; TDV 'Yahya al-Shirvani'.)
