Shmuel Aba is addressed in the correspondence of the Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, as a respected individual of notable character and lineage ("ben kedoshim"—descendant of the righteous). The Rebbe refers to him with honorifics, indicating a relationship of mutual respect and communal involvement.
The letter from the Rebbe to Shmuel Aba acknowledges receipt of several prior letters and apologizes for the delay in response, which was due to the Rebbe's wish to return the original letters after making copies. The tone is warm and considerate, with the Rebbe expressing gratitude for Shmuel Aba's involvement in the matter of a Sefer Torah (Torah scroll). The Rebbe extends heartfelt blessings as the Jewish month of Kislev begins—a time associated with miracles and redemption—emphasizing the importance of spreading both material and spiritual light. He encourages Shmuel Aba to recite the blessing of Shehecheyanu with genuine joy, reflecting on the positive and uplifting nature of the occasion. The correspondence concludes with wishes for good health and a request for confirmation of receipt of enclosed letters.
