Jund Filastin
Jericho, by then named "Ariha" in Arabic variation, became part of Jund Filastin ("Military District of Palestine"), part of the larger province of Bilad al-Sham. The Arab Muslim historian Musa b. 'Uqba (died 758) recorded that caliph Umar ibn al-Khattab exiled the Jews and Christians of Khaybar to Jericho (and Tayma).
