Najm ad-Dīn Abū Ḥafṣ 'Umar ibn Muḥammad an-Nasafī (‎; 1067–1142) was a Muslim jurist, theologian, mufassir, muhaddith and historian. A Persian scholar born in present-day Uzbekistan, he wrote mostly in Arabic. Works He authored around 100 books in Hanafi jurisprudence, theology, Quran exegesis, Hadith and history. Theology Al-'Aqa'id al-Nasafiyya () or Aqa'id al-Nasafi () is his most celebrated work in Kalam, which alongside Al-Fiqh Al-Akbar () of Abu Hanifa and Al-'Aqeedah al-Tahawiyya () of Abu Ja'far al-Tahawi is one of the three seminal works in Sunni Islamic creed. By the 17th-century, more than fifty commentaries were written on this work, of which the most famous is al-Taftazani's commentary named Sharh 'Aqaid al-Nasafi (). Abu Hafs an-Nasafi wrote the Al-'Aqaid as a direct summary of Al-Tamhid le Qawa'id al-Tawhid (), the famous book by his own teacher Abu al-Mu'in al-Nasafi. While a few Arabic sources are sceptical about attributing this work to Abu Hafs an-Nasafi, a recently discovered manuscript of the Persian version of the work confirms the authorship of the work for Abu Hafs al-Nasafi. The Persian version of the work, titled Bayan-e Itiqad-e Ahl-e Sunnat wa Jama'at''' (), is reported on the authority of Al-Nasafi's most famous student, Burhan
