The Jewish tribes of Arabia were Arabian tribes professing the Jewish faith that inhabited the Arabian Peninsula before and during the advent of Islam. It is not always clear whether they were originally Israelite in ancestry, genealogically Arab tribes that converted to Judaism, or a mixture of both. In Islamic tradition the Jewish tribes of the Hejaz were seen as the offspring of the ancient Israelites.: According to Muslim sources, they spoke a language other than Arabic, which Al-Tabari claims was Persian. This implies they were connected to the major Jewish center in Babylon.: Certain Jewish traditions records the existence of nomadic tribes such as the Rechabites that converted to Judaism in antiquity. The tribes collapsed with the rise of Islam, with many either converting or fleeing the Arab peninsula. Some of those tribes are thought to have merged into Yemenite Jewish community, while others, like the residents of Yatta consider themselves Islamized descendants of Khaybar, a Jewish tribe of Arabia.
