How many Kuffar were killed in the Battle of Banu Qurayzah? I have heard that they were nine hundred.
Imam Ibn Ishaq (rahimahullah) the famous Historian, has cited a narration which suggests that the Kuffar who were killed were approximately six hundred or seven hundred. He further states some suggest that were eight or nine hundred.
(Refer: Tarikhul Umam Wal Muluk of Imam Ibn Jarir At Tabari, vol. 1 pg. 515 and Al Fusul Fi Siratir Rasul of Hafiz Ibn Kathir, pg. 175 )
And Allah Ta’ala Knows best.
