`Abdu'l-Bahá

ʻAbdu'l-Bahá, born ʻAbbás, was the eldest son of Baháʼu'lláh, founder of the Bahá’í Faith, who designated him to be his successor and head of the Baháʼí Faith from 1892 until 1921. ʻAbdu'l-Bahá was later cited as the last of three "central figures" of the religion, along with Baháʼu'lláh and the Báb, and his writings and authenticated talks are regarded as sources of Baháʼí sacred literature.
