# Ibadi Islam and Shia Islam: a Diptych comparison

Schema version 1.0. The Diptych displays; it does not score, rank, or adjudicate.

## 1. In its own words

### Ibadi Islam

Ibadi Islam descends from the Kharijite secession of the first Islamic century, moderated early into a tradition of elected imams, congregational discipline, and quiet endurance. It is neither Sunni nor Shia, and it survives as the majority tradition of Oman with communities in North and East Africa.

### Shia Islam

Shia Islam began as the party of Ali and became a family of traditions ordered by the Imamate: the line of divinely guided Imams through whom the Prophet's authority continued. Its Twelver, Ismaili, and Zaidi branches divided over the succession within that line.

## 2. Scale and spread

### Ibadi Islam

Ibadi Islam counts a few million adherents. Oman is its demographic and scholarly center, where Ibadis form a large share of the population, with older communities in Algeria's M'zab valley, Libya's Nafusa mountains, Tunisia's Djerba, and Zanzibar.

### Shia Islam

Shia Islam counts roughly 150 to 200 million adherents, about ten to thirteen percent of all Muslims. Shia form majorities in Iran, Iraq, Bahrain, and Azerbaijan, with large communities in Lebanon, Yemen, Pakistan, India, and Afghanistan.

## 19. What this comparison cannot settle

### Ibadi Islam

This comparison sets two self-descriptions side by side; it does not decide between them. A tradition is a living range of positions, and each panel renders the range this site has documented, which is not the whole of the tradition. Where a cell is marked not yet documented, the gap belongs to this site's documentation, not to the tradition. Questions of truth between the panels turn on premises the reader brings: what counts as evidence, what authority is recognized, and what a human life is for. The instrument does not score, rank, or adjudicate.
