Shâzelî Ali Dede was a 17th-century Sufi sheikh of the Shâdhiliyya order. According to the sources he came from Africa to Istanbul (Erenköy), then settled near the Halîlürrahman complex in Urfa where he founded a lodge; he is said to descend from Abu'l-Hasan al-Shâdhilî, founder of the order. An inscription in his tomb records that Sultan Murad IV visited his lodge in 1639 during the Baghdad campaign, and a decree of Mehmed IV and a 1651 diploma recognized him as a pîr of the Shâdhiliyya. His tomb lies in the cemetery east of the Halîlürrahman Mosque, and his descendants served the lodge with the title 'Sheikh of Halîlürrahman.'
