Text Snapshot

The Arukh HaShulchan states: "אבל המגן אברהם כתב דהו"א מן התורה. ולא ירדתי לסוף דעתו דהא גמרא מפורש בפרק כל שעה דקדוש היום דאורייתא והבדלה מדרבנן" (Arukh HaShulchan, Orach Chaim 266:17).

• Dikduk/Leshon: The phrase "ולא ירדתי לסוף דעתו" ("I did not descend to the end of his opinion") is a classic idiom for expressing strong disagreement, implying the Magen Avraham's position is difficult to reconcile with basic sugyot and lacks a clear textual foundation.

Readings

• Magen Avraham (Orach Chaim 266:1): Posits that Havdalah al HaKos is mi'd'Oraita, drawing an analogy from Kiddush, which is also mi'd'Oraita and requires a cup. This chiddush significantly elevates the obligation.
• Arukh HaShulchan (Orach Chaim 266:17): Vigorously refutes the Magen Avraham, emphasizing that the Gemara (Pesachim 106a) explicitly differentiates Kiddush (d'Oraita) from Havdalah (d'Rabbanan). He contends that the Magen Avraham's premise contradicts foundational Talmudic understanding.

Friction

• Kushya: How could the Magen Avraham assert Havdalah al HaKos is d'Oraita given the explicit Gemara in Pesachim 106a stating "קדוש היום דאורייתא והבדלה מדרבנן"? This seems a direct contradiction.
• Terutz: Some interpret the Magen Avraham's intent not as the entire Havdalah being d'Oraita, but specifically the Havdalah al HaKos itself being a takana that Chazal instituted for pirsumei nisa and chavivut mitzvah, which nevertheless completes a d'Oraita distinction. However, the Arukh HaShulchan rejects this nuance, viewing it as a straightforward claim of a d'Oraita chiyuv for the cup, contrary to the Gemara's plain sense (Arukh HaShulchan, Orach Chaim 266:17).

Intertext

• Pesachim 106a: The sugya explicitly states, "קדוש היום דאורייתא והבדלה מדרבנן" – a core textual basis for the Arukh HaShulchan's critique.
• Rambam, Hilchot Shabbat 29:1: "מצות עשה מן התורה לקדש את יום השבת בדברים... וכן להבדיל במוצאי שבת בדברים" – The d'Oraita component is the verbal distinction ("בדברים"), not necessarily on a cup, supporting the d'Rabbanan nature of the cup.

Psak/Practice

The psak generally follows the Arukh HaShulchan and the vast majority of poskim that Havdalah al HaKos is mi'd'Rabbanan. One who has recited Ata Chonantanu in Tefillah may perform Melacha before Havdalah al HaKos, as the primary d'Oraita distinction has been made (Shulchan Aruch, Orach Chaim 299:10). The cup is a hiddur and a takanat Chachamim.

Takeaway

The Arukh HaShulchan's rigorous textual analysis serves as a powerful reminder that even respected Acharonim are subject to critical scrutiny when their views diverge from explicit Gemara. The chiyuv of Havdalah is primarily the verbal distinction, with the cup being a Rabbinic enhancement.
