<p style='text-align: justify;'>Recto: letter in Hebrew and Judaeo-Arabic from Abraham b. Saʿadya he-Ḥebroni, on behalf of refugees from Hebron that are now in Bilbays. Abraham writes to Isaac b. Samuel ha-Sefaradi (active ca. 1090-1130 CE) in Fusṭāṭ, concerning the building of a new synagogue in Bilbays, replacing an old synagogue that had been torn down. The entire community joined forces to dismantle the synagogue and rebuild the new building. The letter lists the donations given by members of the community, and describes in detail the surrounding properties and their owners. A muslim judge initially objected to the construction of the new synagogue, so the community tactically rebranded their construction as a ‘home’, to which the judge had no objection.
