Ибн Хордадбех
Not much more is known about Abdallah; he had a son named Abu'l-Qasim Ubaydallah, better known as Ibn Khordadbeh, who was born in 820 in Khurasan and was later raised in Baghdad, where Abdallah probably then resided. He thereafter disappears from sources, and later died at an unknown date in the 9th-century.
