Gulshani

The Gulshani () is a Halvati (Khalwati order) sub-order founded by Pir Ibrahim Gulshani, a Turkmen sufi sheikh from Eastern Anatolia, who died in Egypt. His family roots reaches to Oguzata shah in Azerbaijan.
When the Ottomans conquered Egypt the Gulshani order became popular with serving soldiers of the Ottoman army in Egypt. The order was later carried back to Diyarbakir and Istanbul where several "zawiya"s or "tekke"s were established. One notable such tekke was that of the ancestor of Şamsettin Efendi, Pir Ikmalettin Efendi in Diyarbakir.
Ibrahim Al-Gulshani is buried at the takiyyat in Cairo, which was built in 1519–1524. The building, now abandoned, is included on the World Monuments Fund's 2018 list of monuments at risk.
