It it surprising to me that no one seems to reference the alleged Arabic translation of the Talmud - if that's what the source means - by R. Joseph ibn Abitur, about 1000 years ago, as reported in Sefer Haqabbalah and another source.
"Rabbi Moses of Cordoba had many disciples, among them Rabbi Joseph bar Isaac ibn Satnas (?), known as Abitur; he [explained? translated? wrote a digest?] all of the Talmud into Arabic for the Ishmaelite caliph, known as al-Haqim."
So, we can now consider it mentioned.
