Abu al-Yusr al-Bazdawi (Arabic: أبو الْيُسر الْبَزْدَوي) (c.1030-c.1100), who was given the honorific title of Sadr al-Islam, was a prominent Central Asian Hanafi-Maturidi scholar and a qadi (judge) in Samarqand in the late eleventh century.
[1] The attribution al-Bazdawi indicates that he or his family originated from Bazda or Bazdawa, a small town with a castle on the road between Nasaf and Bukhara.
[3] His grandfather Abu Muhammad 'Abd al-Karim b. Musa al-Bazdawi (d. 390 AH/1000–1001 CE), who was a student of al-Maturidi, and his elder brother Fakhr al-Islam 'Ali b. Muhammad al-Bazdawi (d. 482–483 AH/1089–1090 CE) were leading Hanafi scholars and wrote many books.
[8] The most important of his books which remain is Kitab Usul al-Din (edited with a biographical introduction by Hans-Peter Linss).
[13] After serving for a period of time as a magistrate in Samarqand, he eventually moved to Bukhara and died there in 493 A.H. (1100 A.D.).
