Banu Quraiza, Banu Nadir and Banu Qainuqa were three tribes of the Jews.

Banu Quraiza:
The Qurayza, a tribe who lived in Medina alongside the Muslims, had broken their treaty of non-hostility with the Muslims at the height of the Battle of the Trench, and intended to attack them from within, but before they could, the siege on Madina suddenly ended, leaving the Qurayza alone and caught red-handed. They quickly fortified themselves, and finally surrendered after a 25-day siege of their fort.

Banu Nadir:
The Banu Nadir (Arabic: بَنُو ٱلنَّضِير, Hebrew: בני נדיר) were a Jewish Arab tribe that lived in northern Arabia at the oasis of Medina until the 7th century. They were expelled by Muhammad after The Battle of Uhud against the Quraysh, which the latter instigated to avenge their losses.

Banu Qaynuqa:
The Banu Qaynuqa (Arabic: بنو قينقاع; also spelled Banu Kainuka, Banu Kaynuka, Banu Qainuqa, Banu Qaynuqa) was one of the three main Jewish tribes that originally lived in Medina (now part of Saudi Arabia) before being expelled by the Islamic Prophet Muhammad.
