Error 1: Taking “mā ʿAliyyun illā qāʾim” to deny all of Ali's other virtues. Relative qasr does not require that absolute negation.
Error 2: Confusing attribute-to-bearer restriction with real restriction. The first describes direction; the second describes the basis or scope of exclusivity.
Error 3: Identifying ifrad, qalb, and ta‘yin from surface form alone. These types are determined by the listener's prior belief.
Error 4: Treating any fronted object as certainly exclusive. Fronting may serve several rhetorical ends; context remains decisive.
