Ukeyma Khanum is identified by local tradition and the shrine's inscription as a daughter of the seventh Shia Imam Musa al-Kazim, granddaughter of Ja'far al-Sadiq and sister of Imam Ali al-Rida, said to have fled Abbasid persecution to the Baku region. A mosque was raised over her tomb in the late 13th century by the Shirvanshah Farrukhzad II. The original structure was destroyed by the Bolsheviks in 1936; the present mosque was rebuilt on the same site in the 1990s. NOTE: the descent from Musa al-Kazim rests only on the shrine inscription and devotional tradition, is not independently corroborated by early sources, and is a traditional/devotional identification.
