'Ala' al-Din al-Bukhari (Arabic: علاء الدين البخاري‎), was a Hanafi jurist (faqih), Maturidi theologian, commentator of the Qur'an (mufassir), and a mystic (Sufi). Sa'id Foudah suggest that he followed the Naqshbandi path. He is perhaps best known for issuing a fatwa (a legal ruling) whereby anyone that gives Ibn Taymiyya the title "Shaykh al-Islam" is a disbeliever, and authored a book against him entitled "Muljimat al-Mujassima" (Arabic: ملجمة المجسمة‎, lit. 'Curbing the Anthropomorphists'). He was praised by some scholars of his time, like Ibn Hajar al-'Asqalani, and Badr al-Din al-'Ayni.
