Sadr ad-Dīn Abu'l Ḥasan ʿAlī Ibn Abī al-ʻIzz (Arabic: صَدرُ الدين أبو الحسن عليُّ بن علاءِ الدين الدمشقي الصالحيَّ) was a 14th-century Arab Muslim scholar. He was a jurist of the Hanafi school and was nicknamed Qāḍī al-Quḍāh (the Judge of Judges). He served as a qadi in Damascus and Egypt. Many who have written on his biography mentioned that he had vast knowledge, he had a high status and position, and that he was a Faqeeh (expert in Fiqh). He taught at schools and he assumed the office of judge in Damascus and then in Egypt. He is best known for authoring his magnum opus on al-Tahawi's creedal treatise Al-Aqidah al-Tahawiyyah.
