Mishneh Torah, Hilchot Shabbat 3:10:3:

וְהוּא שֶׁלֹּא הִנִּיחַ הַקְּדֵרָה עַל גַּבֵּי קַרְקַע. אִם הִנִּיחַ עַל גַּבֵּי קַרְקַע, אָסוּר לְהַחֲזִיר אֲפִלּוּ לְכִירָה גְּרוּפָה וּקְטוּמָה.

And that one did not place the pot on the ground. If one placed it on the ground, it is forbidden to return it, even to a range that was cleared or covered [of coals]. Dikduk/Leshon nuance: The phrase "והוא שלא הניח" (and that he did not place) introduces a crucial qualification to the preceding leniency, emphasizing that this specific action negates the permission. "על גבי קרקע" (on the surface of the ground) is distinct from other surfaces, suggesting a unique halachic implication.

Readings

Ohr Sameach

The Ohr Sameach explains that placing the pot on the ground, especially if one intended to use its contents, signifies a definitive "completion of the first shehiyah" (נגמרה שהי' הראשונה). This makes any subsequent return a new act, rather than a continuation, thereby breaking the chain of permissibility that chazarah relies upon.¹Ohr Sameach on Mishneh Torah, Sabbath 3:1:1 s.v. דעת דאיכא תרי טעמי.

Steinsaltz

Rabbi Adin Steinsaltz concisely states that placing the pot on the ground "ניכר שעדיין הוא ממשיך את ההשהיה הראשונה" (it is discernible that he is still continuing the initial shehiyah). By contrast, placing it on the ground implies the cessation of the initial shehiyah, making a return problematic.²Steinsaltz on Mishneh Torah, Sabbath 3:10:3 s.v. והוא שלא הניח.

Friction

• Kushya: What is the unique halachic significance of "ground" (קרקע) compared to, say, a table or chair? Both involve removing the pot from the heat.
• Terutz: The distinction lies in the concept of hesech da'at (diverting one's attention) or mikhzei k'meishehev (appearing to cook anew). Placing a pot on the ground is considered a more definitive act of hesech da'at than, for example, holding it or placing it temporarily on an elevated surface. It signals a "finality" to the initial shehiyah, making its return appear as a fresh act of cooking.³Shabbat 38b; see also Rashi, Shabbat 38b s.v. עודן בידו. This is reinforced by the Gemara's discussion of R' Huna, where the act of placing a cup on the ground after serving implies a full detachment.

Intertext

• Shabbat 38b: This Gemara is the direct source, differentiating between a pot "עודן בידו" (still in one's hand) and "הניחו על גבי קרקע" (placed it on the ground) for the purpose of chazarah.
• Shulchan Aruch, Orach Chayim 253:2: Codifies the Rambam's ruling verbatim: "וכל שלא הסיח דעתו ממנו מותר להחזירו, והוא שלא הניחו על גבי קרקע" (And anything from which one did not divert his attention, it is permitted to return, provided he did not place it on the ground).

Psak/Practice

The Rambam's stringent ruling, codified by the Shulchan Aruch, is widely accepted. Therefore, for food to be returned to a heat source on Shabbat, one must not have placed the pot on the ground. Many poskim extend "ground" to any surface that signifies a complete detachment or hesech da'at, such as a kitchen counter, unless one maintained a clear intent to return it and did not set it down as if finishing with it.⁴See Mishnah Berurah 253:56 for an overview of various opinions on "ground" and intent.

Takeaway

The prohibition of chazarah for a pot placed on the ground underscores that hesech da'at, as expressed through a seemingly minor physical act, can fundamentally alter the halachic status of an action on Shabbat, transforming a permitted continuation into a forbidden new act.
