Mishneh Torah, Sabbath 25
Sugya Map
The laws of muktzeh (literally, "set aside" or "excluded") on Shabbat constitute one of the most intricate rabbinic superstructures in all of halachic literature. Far from a mere list of forbidden items, the taxonomy of muktzeh is a profound study in the relationship between human intent (da'at), physical utility (kli), and the sanctified boundary of Shabbat. In Chapter 25 of Hilchot Shabbat, the Rambam maps this territory with characteristic structural precision.
The primary issues, their corresponding nafka minot (halachic ramifications), and their foundational talmudic sources can be mapped as follows:
The Taxonomy of Utensils (Keilim):
- The Core Issue: How do we categorize physical objects that straddle the line between permitted and forbidden labor? The Sages divided utensils into Kli Shemelachto Leheter (a utensil whose primary function is permitted, e.g., a cup) and Kli Shemelachto Le'issur (a utensil whose primary function is forbidden on Shabbat, e.g., a hammer or a millstone).
- The Nafka Mina: The degree of freedom allowed in moving them. A Kli Shemelachto Leheter may be moved for its own sake (le-tzorech gufo—to use it), for the sake of its place (le-tzorech mekomo—to clear the space it occupies), or to protect the utensil itself from damage (le-tzorech ha-kli—e.g., from the sun or rain). A Kli Shemelachto Le'issur, however, may only be moved le-tzorech gufo or le-tzorech mekomo; moving it to protect the object itself remains strictly forbidden.
- Primary Sources: Shabbat 122b, Shabbat 123a, and Shabbat 124b.
The Severity of Financial Loss (Muktzeh Machmat Chisron Kis):
- The Core Issue: What is the status of highly valuable, delicate, or professional instruments that the owner strictly designates for their specific (usually forbidden) task and never uses for casual, alternative purposes?
- The Nafka Mina: These items (e.g., a slaughtering knife, a carpenter’s plane) are classified as Muktzeh Machmat Chisron Kis. Their exclusion is absolute; they may not be moved under any circumstances—not even le-tzorech gufo or le-tzorech mekomo.
- Primary Sources: Shabbat 123a and Shabbat 157a.
The Metaphysics of Twilight (Migo De'itkatzai):
- The Core Issue: Does an object's status at the moment of twilight (bein hashmashot—the transition into Shabbat) lock its status for the entirety of the day?
- The Nafka Mina: If a lamp was burning at twilight, it was forbidden to be moved at that moment because it served a forbidden function (holding a flame). Under the rule of migo de'itkatzai bein hashmashot, itkatzai le-chula yoma (since it was set aside at twilight, it is set aside for the entire day), the lamp remains muktzeh even after the flame is extinguished.
- Primary Sources: Shabbat 44a, Shabbat 141b, and Beitzah 26b.
Indirect Movement (Tiltul Min HaTzad) and Bases (Basis):
- The Core Issue: How do we treat composite scenarios where a permitted object and a forbidden object are physically conjoined or resting upon one another?
- The Nafka Mina: Under what conditions does a permitted object (e.g., a table or pillow) become a basis le-davar ha-asur (a base for a forbidden object), thereby acquiring the forbidden status of the muktzeh resting upon it? Conversely, when is tiltul min hatzad (moving a forbidden object indirectly by moving a permitted one) permitted to salvage food or space?
- Primary Sources: Shabbat 141b–Shabbat 142b and Eruvin 77a.

Text Snapshot
To appreciate the Rambam’s linguistic and conceptual precision, we must examine the opening lines of Hilchot Shabbat 25:1-3, alongside his formulation of muktzeh machmat issur in Halacha 10.
א יֵשׁ כֵּלִים שֶׁמְּלַאכְתָּם לְהֶתֵּר, וְיֵשׁ כֵּלִים שֶׁמְּלַאכְתָּם לְאִסּוּר. כֵּיצַד? כְּלִי שֶׁמְּלַאכְתָּם לְהֶתֵּר--כְּגוֹן כּוֹס לִשְׁתּוֹת בּוֹ, וּקְעָרָה לֶאֱכל בָּהּ, וְסַכִּין לַחְתּךְ בָּהּ בָּשָׂר אוֹ לֶחֶם, וְקַרְדֹּם לִפְצֹעַ בּוֹ אֱגוֹזִים, וְכַיּוֹצֵא בָּהֶן.
ב וּכְלִי שֶׁמְּלַאכְתָּם לְאִסּוּר--כְּגוֹן מַכְתֶּשֶׁת וְרֵחַיִם וְכַיּוֹצֵא בָּהֶן, שֶׁאָסוּר לִכְתּשׁ וְלִטְחוֹן בָּהֶן בַּשַּׁבָּת.
ג כָּל הַכֵּלִים שֶׁמְּלַאכְתָּם לְהֶתֵּר... מֻתָּר לְטַלְטְלָן... בֵּין לְצֹרֶךְ הַכְּלִי, בֵּין לְצֹרֶךְ מְקוֹמוֹ, בֵּין לְגוּפוֹ...
Philological and Grammatical Nuances
"וְקַרְדֹּם לִפְצֹעַ בּוֹ אֱגוֹזִים" (A hatchet to crack open nuts): As noted in many manuscript variations of the Mishneh Torah, some older versions read "פטיש" (a hammer) instead of "קרדום" (a hatchet). The Steinsaltz commentary on this halacha points out that a blacksmith's hammer is typically categorized as a Kli Shemelachto Le'issur (since its primary weekday function is building or metalwork, which are forbidden labors on Shabbat). By swapping or specifying a hatchet (קרדום) used for cracking nuts, or by defining a specific domestic nut-hammer, the Rambam avoids the ambiguity of a heavy industrial hammer. The choice of the verb לפצוע (literally "to wound" or "to cleave") rather than לשבור (to break) underscores a precise linguistic style: it denotes the controlled splitting of a shell without crushing the edible interior.
"בֵּין לְצֹרֶךְ הַכְּלִי... בֵּין לְגוּפוֹ": Note the Rambam’s trichotomy of movement for a Kli Shemelachto Leheter:
- Le-tzorech ha-kli (for the sake of the utensil—e.g., moving it out of the sun so it won't warp).
- Le-tzorech mekomo (for the sake of its space—e.g., clearing a chair to sit down).
- Le-gupo (for its body/use—e.g., picking up a cup to drink).
The phrase le-gupo (literally "for its body") is highly specific. While the Talmud often uses le-tzorech gufo (for its need), the Rambam shifts to le-gupo to emphasize that the movement is driven by the intrinsic physical utility of the cheftza (the object itself).
Let us now look at the pivotal formulation of muktzeh machmat issur in Halacha 10:
י כָּל כְּלִי שֶׁהֻקְצָה מֵחֲמַת הָאִסּוּר--אָסוּר לְטַלְטְלוֹ. כְּגוֹן נֵר שֶׁהִדְלִיקוּ בּוֹ בַּשַּׁבָּת, וּמְנוֹרָה שֶׁהָיָה עָלֶיהָ נֵר, וְשֻׁלְחָן שֶׁהָיוּ עָלָיו מָעוֹת--אֲפִלּוּ כָּבָה הַנֵּר, וַאֲפִלּוּ נָפְלוּ הַמָּעוֹת, הֲרֵי זֶה אָסוּר לְטַלְטְלָן. שֶׁכָּל כְּלִי שֶׁנֶּאֱסַר לְטַלְטְלוֹ בֵּין הַשְּׁמָשׁוֹת, נֶאֱסַר לְכָל הַשַּׁבָּת כֻּלָּהּ...
- "נֵר שֶׁהִדְלִיקוּ בּוֹ בַּשַּׁבָּת" (A lamp that was kindled for the Sabbath): Steinsaltz clarifies that this refers specifically to "a vessel containing a wick that was burning at the onset of Shabbat." The verb הדליקו (they kindled) is in the past tense, yet it is linked to בַּשַּׁבָּת (on the Sabbath). The meaning is: a lamp that was lit prior to Shabbat and continued to burn into the holy day, thereby establishing its status during twilight (bein hashmashot). The transition from a dynamic state of burning to a static state of muktzeh is the core metaphysical mechanism of itkatzai.
Readings
The structural elegance of the Rambam's codification of muktzeh masks several profound conceptual rifts between the primary Rishonim and Acharonim. Unpacking these commentaries reveals the lomdishe (conceptual) machinery of the sugya.
1. The Baseline of Permission: Maggid Mishneh vs. the Vilna Gaon (Gra)
A fundamental question arises regarding the status of Kli Shemelachto Leheter (KSL"H). The Rambam writes in Halacha 1 that these permitted utensils may be moved le-tzorech ha-kli, le-tzorech mekomo, o le-gupo.

│ klal" is forbidden. │ │ permitted vessel allows │
│ │ │ absolute movement. │
└──────────────────────────┘ └──────────────────────────┘
The Maggid Mishneh poses a crucial limit on this permission:
"הרי זה מורה שאין אנו מתירין לטלטל כלי שמלאכתו להיתר אלא לצורך קצת, אבל שלא לצורך כלל—אסור." "This indicates that we do not permit carrying a utensil used for permitted purposes except for some need, but for no purpose at all, it is forbidden." [^1]
This interpretation is codified by the Shulchan Aruch in Shulchan Aruch, Orach Chayim 308:4, establishing that "tiltul she-lo le-tzorech klal" (carrying for absolutely no purpose) is forbidden even for permitted vessels.
The Vilna Gaon (Biur HaGra ad loc.), however, sharply dissents. The Gra argues that the very definition of a Kli Shemelachto Leheter is that its "readiness" (hachana) for Shabbat is absolute. If an object is fully prepared for Shabbat, the act of moving it cannot be rabbinically prohibited, even if done completely mindlessly or for no purpose whatsoever.
The conceptual battle here is between two understandings of muktzeh:
- The Maggid Mishneh's View (Subjective/Gavra-centric): The prohibition of muktzeh is a restriction on the person's actions on Shabbat. Therefore, any movement of any object must be justified by a human need (tzorech). Without a tzorech, the act of carrying violates the restfulness of Shabbat (shevitah).
- The Gra's View (Objective/Cheftza-centric): The prohibition of muktzeh is an objective status of the object. If the object is not muktzeh, it is completely "profane" (in the sense of being accessible) and behaves exactly as it does during the week. The requirement of tzorech is not a general gatekeeper for physical movement; it is merely a specific key required to unlock objects that are otherwise restricted (like Kli Shemelachto Le'issur).
2. The Mechanics of Muktzeh Machmat Issur: Yitzchak Yeranen, the Rosh, and the Taz
In Halacha 10, the Rambam codifies the category of Muktzeh Machmat Issur (set aside due to a prohibition), using the classic talmudic example of a lamp that was lit at the onset of Shabbat.
The author of the commentary Yitzchak Yeranen [^2] notes a major difficulty in the classic codification of this sugya. In Shabbat 157a, the Talmud states that we rule in accordance with Rabbi Shimon, who famously rejects the stringent categories of muktzeh advocated by Rabbi Yehudah. Rabbi Shimon only admits to muktzeh in two extreme cases:
- Muktzeh machmat chisron kis (items excluded due to financial loss).
- Ner she-hidliku bo be-Shabbat (a lamp that was lit at twilight).
The Rosh (Rabbenu Asher), writing in Chullin 15a (Perek Kol HaBasar), states:
"ואנן קיימא לן כרבי שמעון דלית ליה מוקצה מחמת איסור אלא בנר שהדליקו בשבת דדחייה בידים..." "And we hold like Rabbi Shimon, who does not have the category of 'muktzeh machmat issur' except in a lamp that was lit on Shabbat, where he actively pushed it away with his hands..."
The Yitzchak Yeranen points out a glaring logical knot. If we rule like Rabbi Shimon, and Rabbi Shimon rejects the broad category of muktzeh machmat issur—accepting only the specific, localized anomaly of the lit lamp—why does the Rambam formulate a broad, generalized category called "All utensils that were set aside because of a prohibited activity are forbidden to be carried" (כל כלי שהוקצה מחמת האיסור)?
To resolve this, the Yitzchak Yeranen cites the Taz (Turei Zahav, Orach Chayim 279) and the Bach (Bayit Chadash). They explain that even Rabbi Shimon, who generally permits items that were involved in a forbidden state, agrees to the prohibition of muktzeh machmat issur when there is an act of dechei be-yadayim (active, physical exclusion). When a person lights a lamp before Shabbat, knowing it must burn into Shabbat and cannot be touched, they have actively and physically designated that vessel for a forbidden purpose at the critical moment of twilight (bein hashmashot). This is not passive muktzeh; it is an act of conscious exclusion by the gavra (the person).
Thus, the Rambam's category of Muktzeh Machmat Issur is not a betrayal of the ruling in favor of Rabbi Shimon. Rather, it is a precise definition of what Rabbi Shimon himself admits: any utensil that was actively designated for a prohibited function at twilight, such that it could not be used for a permitted function at that exact moment, becomes locked in its forbidden status for the duration of the day.
3. The Rationale of the Lit Lamp: Perush HaMishnayot vs. the Yad
The Yitzchak Yeranen further highlights a fascinating tension between the Rambam’s early writings and his final halachic formulation in the Mishneh Torah.
In his Commentary on the Mishnah (Perush HaMishnayot, Shabbat 3), the Rambam explains that Rabbi Shimon forbids moving a burning lamp because of the concern of shema yichbeh—the fear that by moving the lamp, the oil will tilt away from the wick and the person will accidentally extinguish the flame (violating the Torah prohibition of Mechabeh).
However, in the Yad (Hilchot Shabbat 25:10), the Rambam omits the rationale of shema yichbeh entirely. Instead, he attributes the prohibition to the objective metaphysical status of Muktzeh Machmat Issur and the rule of migo de'itkatzai:
"שכל כלי שנאסר לטלטלו בין השמשות, נאסר לכל השבת כולה..." "For any utensil that was forbidden to be carried at twilight, is forbidden for the entire Sabbath..."
The Merkavat HaMishneh [^3] is deeply troubled by this shift. Why did the Rambam abandon the practical, physical fear of shema yichbeh in favor of the formalistic rule of migo de'itkatzai?
The Yitzchak Yeranen resolves this beautifully: The Rambam’s two explanations do not contradict; they address two distinct phases of the timeline.
- While the lamp is still burning: The primary, immediate prohibition against moving it is indeed shema yichbeh (as formulated in the Perush HaMishnayot). This is a functional prohibition based on the laws of Melacha.
- After the lamp has been extinguished: Once the flame is gone, the fear of shema yichbeh is no longer relevant. Why, then, does it remain forbidden? It is here that the formalistic laws of muktzeh must be invoked. The Rambam in the Yad is codifying the law of the extinguished lamp (אפילו כבה הנר). To explain why an extinguished lamp remains forbidden, the Rambam must transition from the functional rationale of shema yichbeh to the structural, metaphysical rule of migo de'itkatzai bein hashmashot.
Friction
The study of muktzeh is filled with conceptual friction. The most formidable clash in Chapter 25 centers on the Rambam's treatment of Kli Shenishbar (broken utensils) and its compatibility with his stance on Nolad (newly created entities).
The Kushya: The Paradox of Kli Shenishbar
In Halacha 12, the Rambam writes:
יב ...וְכֵן כָּל כְּלִי שֶׁמֻּתָּר לְטַלְטְלוֹ שֶׁנִּשְׁבַּר בַּשַּׁבָּת אוֹ קֹדֶם הַשַּׁבָּת--מֻתָּר לְטַלְטֵל שְׁבָרָיו, בִּלְבַד שֶׁיִּהְיוּ הַשְּׁבָרִים רְאוּיִים לַעֲשׂוֹת בָּהֶן מֵעֵין מְלָאכָה שֶׁהָיוּ עוֹשִׂין בָּהֶן...
"...Similarly, whenever a utensil that can be carried on the Sabbath breaks, whether before the Sabbath or on the Sabbath, its broken pieces may be carried on the Sabbath, provided these pieces can be used for a purpose that resembles the purpose for which they could be used [originally]."
This formulation is highly problematic. The requirement that the broken pieces must perform a function resembling their original purpose (מעין מלאכתן הראשונה) is the explicit opinion of Rabbi Yehudah in Mishnah Shabbat 17:5:
"רבי יהודה אומר: בלבד שיהיו עושים מעין מלאכתן..." "Rabbi Yehudah says: Provided they perform a function resembling their original labor..."
The Sages (the Chachamim), however, argue with Rabbi Yehudah. They maintain that the broken pieces may be moved as long as they can perform any constructive, permitted function on Shabbat, even if it has absolutely no connection to the original function of the vessel (e.g., using a shard of a broken kneading trough to cover a small jug).
Here lies the friction: The Rambam consistently rules in accordance with Rabbi Shimon (who agrees with the Chachamim here) that Nolad (an object that transforms or comes into existence on Shabbat) is permitted. He explicitly permits carrying items that have changed their state. Why, then, does the Rambam rule like Rabbi Yehudah—the champion of muktzeh and nolad restrictions—requiring the shard to perform a function resembling its original use?
This apparent contradiction represents one of the most famous challenges to the Rambam's system of muktzeh, discussed extensively by the Maggid Mishneh, the Kessef Mishneh, and later Acharonim.

Terutz 1: The Textual Resolution (Maggid Mishneh / Kessef Mishneh)
The Maggid Mishneh [^4] offers a philological rescue. He asserts that the standard printed editions of the Mishneh Torah contain a critical scribal error. In authentic, precise manuscript copies of the Yad, the word "מעין" (resembling) is entirely absent. The correct text of the Rambam reads:
"בלבד שיהיו השברים ראויים לעשות בהן מלאכה..." "Provided the pieces are fit to perform a labor..."
By omitting the word me'ein, the Rambam’s ruling aligns perfectly with the Chachamim and Rabbi Shimon. As long as the shard has some utility (e.g., using a glass shard to cover a flask), it remains a "utensil" in the eyes of the halacha and is not classified as muktzeh machmat gufo (inherently useless debris). The Kessef Mishneh [^5] confirms this manuscript reading, and it has been widely adopted in modern critical editions of the Yad.
Terutz 2: The Conceptual Resolution (Chazon Ish)
While the textual resolution is historically and philologically satisfying, the Chazon Ish (Orach Chayim 48) [^6] provides a brilliant conceptual defense of the printed text, demonstrating that even if the word me'ein is retained, the Rambam's ruling remains coherent within the framework of Rabbi Shimon.
The Chazon Ish distinguishes between two different modes of transformation on Shabbat:
- Nolad (New Utility): An object that was not usable for a specific purpose at twilight but becomes usable for that purpose on Shabbat. Rabbi Shimon permits this because the object was already in existence; only its functional designation is new.
- Shari'at (Rubbish/Loss of Identity): An object that undergoes such a radical physical destruction that its original identity is completely obliterated.
If a large, beautiful kneading trough is shattered into tiny, jagged splinters, those splinters are no longer "pieces of a kneading trough." They have lost their shem kli (status of being a utensil) entirely and have entered the category of muktzeh machmat gufo (inherently non-functional objects, like common stones).
To prevent an object from falling into the black hole of muktzeh machmat gufo, it must retain some thread of its original identity. This is the meaning of me'ein מלאכתן הראשונה. It is not a restriction based on the laws of nolad; rather, it is a definition of identity continuity. If the shard can perform a function that is conceptually or physically related to its original function (e.g., a piece of a broken food container still serving to cover food), the original shem kli of the vessel survives within the shard. If the shard can only be used for a completely unrelated task (e.g., using a beautifully carved wooden shard merely as a doorstop), the original shem kli is dead, and the shard reverts to being a mere piece of wood—which, like a common stone, is muktzeh machmat gufo.
Through this conceptual distinction, the Chazon Ish harmonizes the printed text of the Rambam with the underlying mechanics of Rabbi Shimon's system:
$$\text{Object Shattered} \implies \begin{cases} \text{Retains functional continuity (} \textit{me'ein} \text{)} & \implies \text{Identity survives} & \implies \text{Permitted} \ \text{No functional continuity} & \implies \text{Identity destroyed (Rubbish)} & \implies \text{Muktzeh Machmat Gufo} \end{cases}$$
Intertext
To fully appreciate how the Rambam's formulations in Chapter 25 operate within the broader tapestry of Halacha, we must examine their talmudic origins and their subsequent codification in the Shulchan Aruch.
1. The Detached Doors of a House: Shabbat 122b
In Halacha 6, the Rambam writes:
ו דַּלְתוֹת הַבַּיִת--אַף עַל פִּי שֶׁהֵן כֵּלִים, לֹא הֻכְנוּ לְתַשְׁמִישׁ; לְפִיכָךְ אִם נִתְּקוּ, וַאֲפִלּוּ בַּשַּׁבָּת--אָסוּר לְטַלְטְלָן.
"The doors of a house are considered to be utensils; they have not, however, been prepared for use. Therefore, if they are detached—even on the Sabbath—they may not be moved."
This ruling is anchored in Shabbat 122b, which draws a sharp distinction between the doors of a chest (דלתות שידה תיבה ומגדל) and the doors of a house.

└──────────────────────────┘ └──────────────────────────┘
The conceptual split between Rashi and the Rambam on this sugya is highly illustrative:
- Rashi's View: Rashi Shabbat 122b s.v. "דלתות הבית" explains that the doors of a house are not considered keilim (utensils) at all. Because they are attached to the ground (mechubar le-karka), they are ontologically classified as "ground" (real estate) rather than "vessels" (movable property). Once they are detached, they are merely pieces of a building, and carrying them is forbidden because they lack the basic definition of a kli.
- The Rambam's View: The Rambam rejects Rashi’s ontological exclusion. He explicitly states that the doors of a house are considered to be utensils (אף על פי שהן כלים). However, they are forbidden because they lack the subjective element of human preparation (lo huchanu le-tashmish). Because they were fixed to a wall, a person never contemplated using them for any mobile purpose on Shabbat.
This difference represents a major chakira (conceptual inquiry) in the definition of muktzeh: Is muktzeh a physical deficiency in the object itself (Rashi—it is not a kli), or is it a psychological deficiency in the owner’s mind (Rambam—it lacks hachana)?
2. The Codification in Shulchan Aruch: Orach Chayim 308 & 311
The Rambam's structural divisions in Chapter 25 serve as the bedrock for the Shulchan Aruch's presentation of the laws of muktzeh.
The Status of Earth and Sand: In Halacha 7, the Rambam writes: "עפר וחול... אין מטלטלין אותן" (Earth and sand... may not be moved). In Halacha 21, he adds the leniency: if a person brought a container of earth into his home and designated a corner for it before Shabbat (ייחד לו קרן זוית), he may use it for his domestic needs.
This is codified verbatim in Shulchan Aruch, Orach Chayim 308:38. The Mishnah Berurah (ad loc. [^7]) notes that this designation transforms the earth from a state of muktzeh machmat gufo (raw, natural material) to a state of מוכן (prepared vessel/utility), demonstrating how human intent (da'at) has the power to elevate raw matter into the category of a permitted vessel.
Indirect Movement (Tiltul Min HaTzad): In Halacha 14, the Rambam introduces the mechanics of tiltul min hatzad through the case of a turnip or radish buried in loose earth with its leaves protruding:
יד ...וְכֵן לֶפֶת אוֹ צְנוֹן שֶׁהוּא טָמוּן בֶּעָפָר וּמִקְצָת עָלָיו מְגֻלִּין--מוֹשְׁכִין אוֹתוֹ בַּשַּׁבָּת, וְאַף עַל פִּי שֶׁהֶעָפָר נִדּוֹד..."...Similarly, if a turnip or a radish is buried in [loose] earth and a portion of its leaves is protruding, one may pull out [the vegetables] on the Sabbath, even though the earth is dislodged."
This is codified in Shulchan Aruch, Orach Chayim 311:8. The Shulchan Aruch limits this permission to loose, unrooted earth. If the vegetables had begun to take root, pulling them would violate the Torah prohibition of Toleh (uprooting/harvesting). This shows how the laws of muktzeh and tiltul min hatzad must always be calibrated against the primary creative labors (Avot Melachot).
Psak/Practice
How do the conceptual categories of Rambam Chapter 25 land in contemporary halachic practice? The rise of modern technology and luxury items has forced contemporary poskim (halachic authorities) to apply the Rambam’s classical taxonomy of muktzeh to entirely new domains.
1. Modern Electronics: Kli Shemelachto Le'issur vs. Muktzeh Machmat Chisron Kis
The classification of electronic devices (smartphones, laptops, tablets) on Shabbat is one of the most pressing questions in modern halacha.

└──────────────────────────┘ └──────────────────────────┘
The Kli Shemelachto Le'issur Argument: A smartphone's primary functions (making calls, writing messages, operating circuits) are strictly forbidden on Shabbat. Therefore, it should be categorized as a Kli Shemelachto Le'issur. Under the ruling in Halacha 3, one would be permitted to move a smartphone le-tzorech mekomo (e.g., if it is resting on a chair where one wishes to sit) or le-gupo (e.g., using the reflective screen as a temporary mirror, or using its weight as a paperweight).
The Muktzeh Machmat Chisron Kis Argument: However, because smartphones are highly expensive, delicate instruments containing sensitive personal data, owners are extremely careful not to use them for crude, non-electronic tasks. A person would never use an iPhone as a physical wedge to prop open a window or as a nutcracker.
Under the Rambam’s definition of Muktzeh Machmat Chisron Kis in Halacha 9:
"כל זמן שאדם מקפיד על הכלי שמא יפחת דמיו... הרי זה אסור לטלטלו..." "Whenever a person is careful [not to use] a utensil lest its value depreciate... carrying it is forbidden..."
Therefore, contemporary consensus (e.g., Shmirat Shabbat Kehilchata [^8]) rules that modern smartphones and laptops are classified as Muktzeh Machmat Chisron Kis. Consequently, they may not be moved on Shabbat under any circumstances—not even le-tzorech mekomo or le-gupo.
2. Meta-Psak Heuristics: Tiltul Min HaTzad in Medical and Security Contexts
The Rambam’s formulation of tiltul min hatzad (indirect movement) in Halachot 14–15 serves as a vital halachic escape valve in contemporary emergency and medical scenarios.
If a medication that is not life-critical (and therefore does not warrant direct desecration of Shabbat under Pikuach Nefesh) is resting inside a drawer alongside muktzeh items (like money or car keys), one may open the drawer and retrieve the medication. Because the primary intent is to access the permitted item (the medicine), the indirect movement of the forbidden items (the drawer and the money resting inside it) is permitted under the guidelines established in Halacha 14.
3. Connection to Rosh Chodesh Tamuz
Today, as we observe Rosh Chodesh Tamuz, we mark the transition into the height of the summer season (Tekufat Tamuz).
The Rambam in Halacha 3 touches on this environmental reality:
"וכן להוציאו מן החמה שלא תתייבש ותשבר..." "Similarly, [a utensil] may be taken out of the sun so that it will not become parched and break."
The halacha permits moving a permitted vessel to protect it from the intense summer heat of Tamuz. This physical permit carries a profound spiritual resonance. Tamuz is historically a month of vulnerability, associated with the cracking of the walls of Jerusalem. The halachic insistence on protecting our keilim (vessels) from being parched and broken by the sun teaches us that during seasons of intense spiritual heat and trial, we must actively guard our spiritual vessels—our homes, our communities, and our commitments—ensuring they remain intact, functional, and ready to receive the light of the upcoming season of renewal.
Takeaway
- The laws of muktzeh are not merely a list of forbidden items, but a delicate calibration of human intent (da'at) and physical utility (shem kli).
- Even the most rigid physical categories of Shabbat rest are deeply responsive to human need, ensuring that the preservation of life, the prevention of animal suffering, and the joy of Shabbat are never eclipsed by formalistic stringencies.
