There is, indeed, more than a mere similarity. Here we have the prototype – indeed, I would suggest, the origin of the story of Banu Qurayza, preserved by descendants of the Jews who fled south to Arabia after the Jewish Wars, just as Josephus recorded the same story for the Classical world. A later generation of these descendants superimposed details of the siege of Masada on the story of the siege of Banu Qurayza, perhaps by confusing a tradition of their distant past with one from their less remote history. The mixture provided Ibn Ishaq’s story. When Muslim historians ignored it or transmitted it without comment or with cold lack of interest, they only expressed lack of enthusiasm for a strange tale, as Ibn Hajar called it.
