More Details About Jews In History That Are Mentioned In Quran
Since all of the dealings with Jews of that time were done with their tribes as a whole, that is why we read more about them via their tribe names. But the names of their leaders/chiefs are also found in histiory books. K aab bin Ashraf was the chief of Banu-Nazeer (who was killed in 3rd Hijri because of his extreme enmity against Muslims). After that, Huyay b. Akhtab was their chief. Similarly, K aab bin Asad was the chief of Banu-Quraiza. You can refer to any good history book like Tarikh-e-Tabri to know more about them.
