Jamal al-Khalwati, known as Chelebi Khalifa (d. 899/1494); his birthplace is disputed in the sources (Amasya or Aksaray). A disciple of Muhammad Baha al-Din al-Arzinjani, he founded the Jamaliyya branch of the Khalwatiyya and, as the order's first great representative in Istanbul under Bayezid II, headed the Koca Mustafa Pasha lodge. He died near Tabuk in 899/1494 while travelling to Mecca for the hajj; the TDV encyclopedia does not firmly specify his grave, and since he is held to have been buried where he died, his Istanbul lodge counts as a maqam and no coordinates are given.
