i recently came across the work of Al-Baqir and was told by a friend that while revered by Shias he is also acknowledged by Sunnis?
Re: Al-Baqir
By Al-Baqir RadiAllahu Anhu do you mean father of Imam Jaffar As Sadiq? If so, and this true for both Father and Son, anything authentically reported from them can be considered Hujjat, a correct a position as you can get. These men are not just Ahle Bayt of RasoolAllah SallAllahu Alaihi wa Ahlihi wa Sallam but also Imams of the Salaf and the Ummat
