I want to know the answer to the following question:
How many members of the Banu Qurayza were beheaded after surrendering to Muhammad and his followers according to Tabari and Ibn Hisham?
All the background I'm provided with is that "Muhammad also ordered another siege on the Banu Qurayza during the Invasion of Banu Qurayza, because according to Muslim tradition he had been ordered to do so by the angel Gabriel.". Is that enough to answer the question?
Answer: no
