Throughout history, various Muslim schools (asides from the Twelver school) have claimed to be the inheritors of Ahlulbait’s legacy. Most classical Shi’ite schools, however, have perished, and only a few remain today. The few surviving schools, nevertheless, all claim to be representative of the teachings of the Prophet’s household.

Twelver orthodoxy today asserts that those who fought ‘Ali ibn Abi Talib (may Allah be pleased with him) were apostates, they excommunicate most of the Sahabah anyway, but in particular the likes of Mu’awiyah, Talha, al-Zubayr, ‘Aisha (may Allah be pleased with them) and other companions of the Prophet (ﷺ) who were in any shape or form opposed ‘Ali ibn Abi Talib.
