The fullest account of the incident records that the people killed were armed soldiers who turned on the Muslims.
Not only is this account not mentioned in any modern account of the events - Montgomery Watt, Maxime Rodinson, et al, but the account (that the Jews were armed and attacked the Muslims) is not mentioned by either Ibn Ishaq or Tabari.
In other words, please try and remain consistent.
Why would Baldhuri ignore the killing of 7000 and only list 4000 captives, and why would John of Nikiu not give any numbers at all? What evidence do we have that Theophanes' numbers for those killed is accurate - he wasn't there after all, and doesn't seem to have given his sources)
Balhaduri's figures for those captured doesn't corroborate the supposed massacre - if anything it goes to show that there wasn't a massacre

Indeed, why would the earliest historian on Muhammad and another historian who is second to only Ibn Ishaq leave out the details your author mentions? From which early historian does he get them from (it isn't Ishaq or Tabari) and if your author does get these accounts from an early historian, why would both Ibn Ishaq and Tabari not include these details in their accounts?
You seem to be full of contradictions. One moment you're pointing out that because a Muslim historian does not mention a massacre (only implies one), the massacre of 7,000 mentioned by Theophanes must be suspect. Yet here you are quoting from a dubious author who does not cite his source nor are the accounts he provides corroborated by two of the earliest and most prolific Muslim historians. So, what does that make your author's version of events?
But hey, why try and remain consistent?
