The Clans
In the name of God, Most Gracious, Most Merciful.
[33:26]
And those of the People of the Book who aided them - God did take them down from their strongholds and cast terror into their hearts. (So that) some ye slew, and some ye made prisoners.


* v.26 : The reference is to the Jewish tribe of the Banu Quraiza. They counted among the citizens of Madinah and were bound by solemn engagements to help in the defence of the City. But on the occasion of the Confederate siege by the Quraish and their allies they intrigued with the enemies and treacherously aided them. Immediately after the siege was raised and the Confederates had fled in hot haste, the Prophet turned his attention to these treacherous "friends" who had betrayed his City in the hour of danger.
* The Banu Quraiza (see last note) were filled with terror and dismay when Madinah was free from the Quraish danger. They shut themselves up in their castles about three or four miles to the east (or north east) of Madinah, and sustained a siege of 25 days, after which they surrendered, stipulating that they would abide by the decision of their fate at the hands of Sad ibn Muaz, chief of the Aus tribe, with which they had been in alliance.
* Sad applied to them the Jewish Law of the Old Testament, not as strictly as the case warranted. In Deut. xx. 10-18, the treatment of a city "which is very far off from thee" is prescribed to be comparatively more lenient than the treatment of a city "of those people, which the Lord thy God does give thee for an inheritance," i.e., which is near enough to corrupt the religion of the Jewish people. The punishment for these is total annihilation: "thou shalt save alive nothing that breatheth" (Deut. xx. 16). The more lenient treatment for far-off cities is described in the next note, According to the Jewish standard, then, the Banu Quraiza deserved total extermination-of men, women, and children. They were in the territory of Madinah itself, and further they had broken their engagements and helped the enemy.
* Sad adjudged them the milder treatment of the "far-off" cities which is thus described in the Jewish Law: "Thou shalt smite every male thereof with the edge of the sword: but the women and the little ones, and the cattle, and all that is in the city, even all the spoil thereof, shalt thou take unto thyself, and thou shalt eat the spoil of thine enemies, which the Lord thy God hath given thee" (Deut. xx. 13-14). The men of the Quraiza were slain: the women were sold as captives of war; and their lands and properties were divided among the Muhijirs.
