محمد الباقر
According to Al-Shahrastani, a dispute had arisen between Muhammad al-Baqir and Zaid because Zaid had been following the Mu'tazilite Wasil ibn Ata. Zaid had also announced that the position of imam was conditional on his appearing publicly to assert his rights. Muhammad al-Baqir replied, "Your faith then is merely in your father, as such, for according to your theory he was not an imam, for he certainly never came forth to assert his claims."
