Inspired by Islamic studies, I came to wonder about the Jewish community in Mecca (Bakkah) in the time of Muhammad.
What "school of thought" did the Jews of Mecca (or Bakkah) follow that time? Did that school of thought have any major differences with other schools of thoughts (that time or today)? Provide some if possible. If this is impossible to answer, what about trying to speculate: If one collects the information about (some) Jewish "beliefs" which exists in the Quran and other reports, and then analyses it (it has to be interpreted correctly too though), one might draw a conclusion or pinpoint that the result given in the analysis is similar to sect X's understanding or some schools of thought have inclined to similar understandings.
