In the ‘Mediterranean Society’ of the Genizah fragments, we find Jews, Christians and Muslims living and working alongside each other. This Jewish legal deed, written in Judaeo-Arabic, documents the sale of a sugar factory, a major industry in Fustat. It was sited in a mixed Muslim and Jewish neighbourhood, and was jointly owned by a Jewish family and a Muslim judge (qadi).
