Why did Muhammad kill the Jewish Bani Qurayze tribe?
Hatun and Daniel discuss why Muhammad killed the Bani Qurayze.
“Narrated ‘Aisha: When Allah’s Apostle returned on the day (of the battle) of Al-Khandaq (i.e. Trench), he put down his arms and took a bath. Then Gabriel whose head was covered with dust, came to him saying, “You have put down your arms! By Allah, I have not put down my arms yet.” Allah’s Apostle said, “Where (to go now)?” Gabriel said, “This way,” pointing towards the tribe of Banu Qurayza. So Allah’s Apostle went out towards them.” Bukhari 4:52:68
