Muhammad al-Baqir
Muhammad al-Baqir is not recognized by Zaidis as Imam, however he is a prominent figure among them; as his traditions appear in some Zaidi works like Amālī al-Imām Aḥmad b. ʿĪsā. According to Kohlberg, al-Baqir appears in Zaidi works as "acknowledging Zayd's superior knowledge and so, by implication, Zayd's claims to the Imamate."
