The Six Articles of Faith: Sunni theology is built upon six core beliefs: (Oneness of God), (Angels), (Holy Books), (Prophethood), (Day of Judgement), and (Predestination).
Leadership and the Caliphate: In Sunni Islam, the Caliph is a political and military leader responsible for upholding the law, but they are not considered divinely inspired or infallible. Religious authority is instead distributed among scholars () who interpret the Quran and Sunnah.
The Five Pillars: Sunni practice is centered on the Five Pillars: (Faith), (Prayer), (Charity), (Fasting), and (Pilgrimage).
Communal Consensus: Sunnis place high value on Ijma (consensus of the community), believing that the collective wisdom of the Muslim body is a safeguard against error.
The Five Roots (Usul ad-Din): Shia theology emphasizes five foundational principles: (Oneness), (Justice of God), (Prophethood), (Leadership), and (Resurrection).
The Concept of the Imam: Unlike the Sunni view, Shias believe the Imam is a divinely appointed successor from the Ahl al-Bayt (Family of the Prophet). The Imam is considered infallible () and possesses unique spiritual authority to interpret the inner meanings of the Quran.
Ten Obligatory Acts: While Shias follow the Five Pillars, they expand their framework into ten acts, including (an additional 20% tax), (struggle), and (enjoining what is right).
Religious Authority: Authority is centralized in the Imams and, during the occultation of the final Imam, in high-ranking scholars known as Ayatollahs who act as representatives.
Identify the Root Cause: When discussing diversity, always trace the split back to the death of the Prophet and the disagreement over succession. This provides the necessary historical context for all subsequent theological differences.
Terminology Precision: Use specific Arabic terms like , , and correctly. Examiners look for the distinction between the Sunni 'Imam' (prayer leader) and the Shia 'Imam' (divinely appointed leader).
Compare and Contrast: Be prepared to list both similarities (e.g., belief in one God, the Quran, and the Prophet) and differences (e.g., the nature of leadership and specific articles of faith).
Avoid Generalizations: Do not assume all Muslims are the same. Acknowledge that while 85-90% are Sunni, the Shia tradition has its own robust legal and theological systems.
