Sharh al-'Aqa'id al-Nasafiyya () is a commentary written by the Hanafi-Shafi'i scholar al-Taftazani (d. 791/1389 or 792/1390) on the creed of Najm al-Din 'Umar al-Nasafi (d. 537/1142-3), an authoritative compendium on Islamic Sunni theology that remained a standard textbook in Ottoman schools. The book is a commentary on al-Nasafi's treatise, in which al-Nasafi systematized Hanafi-Maturidi theology. However, al-Taftazani adopted an Ash'ari perspective in his commentary. 'Aqā'id al-Nasafī 'Aqā'id al-Nasafi, a short summary of the authentic Muslim beliefs by Najm al-Din 'Umar al-Nasafi. 'Aqā'id is the plural of 'aqidah, which means, religious belief, creed, or theology. This short treatise has gained much popularity and acceptance amongst the Islamic community because of its comprehensive summary of the beliefs of Islam.
