Text Snapshot

The Arukh HaShulchan synthesizes the core debate, presenting the Magen Avraham's lenient view:

"ודעת המגן אברהם בסימן רס"ג ס"ק י' דאפילו ביום ששי קודם פלג המנחה מותר להדליק נרות שבת" ^[Arukh HaShulchan, Orach Chaim 266:8]. The leshon "מותר להדליק" explicitly permits lighting even prior to Plag HaMincha, indicating a valid fulfillment of the mitzvah, not merely a b'dieved allowance.

Readings

Magen Avraham ^[Orach Chaim 263:10]

Permits lighting before Plag HaMincha. He distinguishes between kabalat Shabbat for tefillah (e.g., Maariv, which generally requires Plag) and kabalat Shabbat for issur melacha or mitzvot like ner Shabbat, which can be performed earlier. The lighting itself, as a hachanah for Shabbat, is valid.

Taz ^[Orach Chaim 263:4]

Contends that lighting before Plag HaMincha is invalid. His reasoning is that before Plag, it is entirely yom chol, thus one cannot accept Shabbat or perform a Shabbat mitzvah until Plag, which marks the earliest time for tosefet Shabbat.

Friction

Kushya

How can one light ner Shabbat before Plag HaMincha when tosefet Shabbat generally only begins at Plag, and prior to that, it's considered pure chol? Is this not hachanah mi'chol l'chol for a Shabbat mitzvah?

Terutz

The Magen Avraham (followed by the Arukh HaShulchan) posits that while kabalat Shabbat for tefillah or full issur melacha may require Plag, the mitzvah of ner Shabbat functions as a hachanah that can be performed earlier. The act of lighting, with the proper intent for Shabbat, is enough to validate the mitzvah, even if one doesn't fully accept Shabbat l'kula milleta until later.

Intertext

• Berachot 27a: Discusses the concept of Plag HaMincha as the earliest time for kabalat Shabbat for tefillah.
• Shabbat 23b: Establishes ner Shabbat as chovat bayit, a fundamental obligation of the household.

Psak/Practice

The Arukh HaShulchan, concluding with the Magen Avraham, rules that one may rely on this leniency. Thus, b'sha'at ha'tzorech (in a time of need), one can light Shabbat candles before Plag HaMincha. However, one should still be careful not to perform melacha after lighting, as the act of lighting generally signifies kabalat Shabbat l'issur melacha for the individual.

Takeaway

The precise moment of kabalat Shabbat is not monolithic; its application can differ for various mitzvot and prohibitions, highlighting the nuanced nature of halachic time.
