Faith, Prophets, and the Community

Sharh al-Aqa'id an-Nasafiyyah's treatment of faith (iman), prophethood (nubuwwah), and the community's creedal consensus covers the aspects of Islamic theology most directly relevant to everyday religious life. These sections are among the most practically important for Muslim believers and have generated sustained discussion across the centuries of the work's use.

On faith, the Maturidi position as presented by an-Nasafi and explained by at-Taftazani holds that faith consists primarily of inner conviction and verbal affirmation (tasdiq bil-qalb wa iqrar bil-lisan). This differs from some presentations in the Ash'ari tradition that emphasize verbal affirmation, and from the Athari position that includes action as a component of faith. The Maturidi school held that a Muslim who has sincere inner conviction but fails to perform actions remains a Muslim — though a sinful one — because the actions, however obligatory, are not constituents of faith itself.

At-Taftazani explains that faith does not increase or decrease in the Maturidi view — faith is complete conviction, and complete conviction does not admit of degrees. This is another point of difference from the Athari tradition, which held that faith increases with obedience and decreases with sin. The Maturidi position is that what increases and decreases is the quality and fruits of faith — the tranquility, the dedication, the spiritual benefit — not faith itself, which is either present or absent as complete conviction.

On prophethood, an-Nasafi affirms the complete prophetic line from Adam to Muhammad, the obligation to believe in all prophets and to honor them, and the finality of Muhammad's mission. At-Taftazani's commentary explains the necessary attributes of the prophets — their truthfulness, trustworthiness, and intelligence — and discusses how prophetic preservation from sin (isma) should be understood. The Maturidi position preserved prophets from deliberate deception and major sins but allowed for minor errors and mistakes in worldly judgment.

The sections on the community address the status of the companions of the Prophet, the legitimacy of the first four caliphs, and the proper attitude toward sectarian disputes within the Muslim community. An-Nasafi's statements on these matters are part of the classical Sunni consensus on the respect due to the companions and the validity of the early caliphate, and at-Taftazani's commentary situates them within the larger debate between Sunni and Shia interpretations of early Islamic history. The work's position is clear and consistent with the standard Sunni tradition while avoiding gratuitous polemical sharpness.
