Abu Ishaq al-Saffar al-Bukhari (Arabic: أبو إسحاق الصفّار البخاري), was an important representative of the Sunni theological school of Abu Mansur al-Maturidi (d. c. 333/944) and the author of Talkhis al-Adilla li-Qawa'id al-Tawhid (Arabic: تلخيص الأدلّة لقواعد التوحيد) which is a voluminous kalam work.

His theological works, his method in kalam, and frequent reference to his works by Ottoman and Arab scholars indicate that al-Saffar is a respected and authoritative Hanafi-Maturidi theologian who systematically established his ideas about kalam believing that information based upon reason, revealed knowledge and senses are determinative in his area.

[9][10] The alternative name Ibrahim b. Ishaq, recorded by Brockelmann in his GAL, is found only in the British Museum manuscript no.

[11][12] In his work titled Talkhis al-Adilla li-Qawa'id al-Tawhid on kalām,[Note 1] he wrote extensively about al-Asma' al-Husna (the Most Beautiful Names of God).

In the pre-Saffar Hanafi-Maturidi theological literature, there was no other work that addressed al-Asma' al-Husna in such an extensive way.
