Page "Medina" Paragraph 19

Into the older Arab town of Yathrib, Jews arrived as refugees in the 2nd century AD in the wake of the Jewish – Roman wars.

There were three prominent Jewish tribes that inhabited the city into the 7th century AD: the Banu Qaynuqa, the Banu Qurayza, and Banu Nadir.

Ibn Khordadbeh later reported that during the Persian Empire's domination in Hejaz, the Banu Qurayza served as tax collectors for the shah.
