Whirling dervish children practise as they wait to perform at the Blue Mosque Square in Istanbul, Turkey, 30 September 2023. About 750 whirling dervishes took part in the event in front of the Hagia Sophia Mosque, marking the 750th death anniversary of Mevlana Jalaluddin al-Rumi, a 13th-century Sufi mystic, poet and Islamic scholar, who is buried in Turkey's central province of Konya, where he lived most of his life.
