The Baha’i canon includes original scriptures handwritten by the Bab and Baha’u’llah, as well as authoritative interpretations by Baha’u’llah’s son ‘Abdu’l-Baha and great-grandson, Shoghi Effendi. Much of this canon was written in Arabic and Farsi. These original writings are available for research by scholars. Because the Baha’i Faith places great value on independent investigation, Baha’i administration oversees authorized translations into both mainstream and indigenous languages globally.
