After the battle of the trench, the Banu Quraiza were condamened by Mohamed on the order of
Gabriel. Adults males were executed (Adults were the ones who grown
pubes or
pubic hair). Women and children were enslaved (4028). You can have more information in the Quran (see
33:26, especialy the tafsir of Ibn Kathir).
If any muslims imitate the prophet today, by executing male and enslaving women and children, are they still a good muslim?
