Two guides for careful comparison
Branches, beliefs & scripture
Understand Muslim communities, religious authority and the transmission of the Qur’an. Start with the distinction that matters to your question.
A branch, a school of law, a reading tradition and a translation describe different things. These guides explain what can be counted, where the differences arose and how religious and historical scholarship approach them.
How many branches of Islam are there?
Sunni and Shia are the two largest branches of Islam; Ibadi Islam is another longstanding branch. A total of every sect depends on how the term is defined. Legal schools, theological traditions and Sufi orders overlap, so adding them together produces a misleading count.
Read the guide ↗Scripture & transmissionOne Qur’an, different readings: what does that mean?
Mainstream Sunni and Shia Muslims use the same 114-surah Qur’anic collection. The standard Sunni classification recognizes ten canonical reading traditions, each with two principal transmissions. Translations, manuscript variants and hadith collections are further categories that require their own explanations.
Read the guide ↗Three questions to carry into your reading
- Who has authority? Identify the community, teacher or institution whose interpretation is being described.
- What is the source? Distinguish Qur’anic text, hadith, translation and commentary.
- How was it transmitted? Ask what the surviving evidence establishes and where an explanation relies on faith or inference.
