The 73-Sects Hadith
The foundational text: “The Jews divided into 71 sects, the Christians into 72, and my community will divide into 73 — all of them in the Fire except one.” (Narrated in various forms in Abu Dawud, Ibn Majah, al-Tirmidhi.)
When asked which one is the saved sect, different versions give different answers:
- “Those who are on what I and my Companions are today” — emphasizing Sunna and jama’a
- Just “the group” — leaving interpretation open
The hadith is classified by critics as problematic in chain; defenders point to multiple chains that strengthen each other. It became the organizing text for the entire genre of Islamic heresiography.
The Classic Taxonomy
Sunni: The Four Schools + Ash’ari/Maturidi theology + traditional hadith approach. The majority in numbers.
Shi’a: subdivided into:
- Ithna ‘Ashari (Twelver Shi’a): Imam line to the 12th Imam (Muhammad al-Mahdi, in occultation)
- Zaydiyya: Imam must be a public political claimant from the Prophet’s family
- Ismaili: Imam line follows through Ismail ibn Ja’far; Fatimid Imams; present in various branches
Mu’tazila: rationalist theological school; peak under early Abbasids; held Quran was created (not eternal)
Khawarij: extreme position; held that major sin makes one an apostate
The Ismaili Self-Understanding
In Ismaili thought, the 73-sects hadith is read through the lens of the Imam’s guidance: the firqa najiyya (saved group) is the community that maintains walayah to the living Imam — because the Imam is the only reliable guide to what the Prophet and his Companions actually intended. The proliferation of sects is itself evidence that without the Imam’s living authority, the community fragments into contradictory interpretations of the same texts.
