Religious schisms often turn on the meaning of shared doctrine, not its rejection.

Evidence

Like all Muslims, Wahhabis uphold the doctrine of tawḥīd. Unique to Wahhabism is the implementation of tawḥīd al-ibada (servitude), which prohibits commitment to intermediaries or spiritual practises not endorsed by Wahhabi hermeneutics. Intercession by prophets and saints, widespread across other Islamic denominations, is considered a violation of tawḥīd by Wahhabis. The disagreement between Wahhabis and other Muslims is not on tawḥīd, but rather what constitutes tawḥīd. — Wikipedia contributors, Wahhabism, 50

Categorization

• DEEPTHINKING: Reframes sectarian conflict as a war over definitions rather than over fundamentals — applicable far beyond Islam to any schism, legal dispute, or ideological split.
• XREF: Parallels the Ambedkar material where dharma reframed as law rather than religion changes what reform is even conceivable.
