54-2 (The author of the book narrated) my father - may God be pleased with him - narrated that Sa’d ibn Abdullah quoted on the authority of Ahmad ibn Abi Abdullah al-Barqi, on the authority of Abu Hashem Dawood ibn Al-Qasim al-Ja’fari, “I used to eat lunch with Abal Hassan Ar-Ridha’ . Sometimes he  spoke to some of his servants in Slavic and Persian (Farsi) languages. Sometimes I sent my servant who spoke Persian to the Imam  and Ar-Ridha’  knew Persian. Sometimes it became difficult for the servants to understand Persian. Then the Imam  used to explain things for them himself.
