The following chapter will discuss the laws of Muktzah items as they relate to being used for cleaning purposes after going to the bathroom. In addition other laws regarding using the bathroom are dealt with in this chapter. One must keep in mind that the form of using the bathroom back then was much different than today, and thus the laws as set forth here are to be taken in that context. For practical application of these laws see the compilation.
Using stones to wipe with
Using stones to clean oneself with:
Pushing off the Muktzah laws: Out of respect for humanity the Sages permitted to move stones to use to clean oneself with upon going to the bathroom. Even if one had a bowel movement on ones roof and carrying up the stones [to clean oneself with] involves much effort, [nevertheless] it is permitted.
How many stones may one bring with him if he has a designated bathroom area? One who has a designated area used as a bathroom, which means that he always uses one specific area to have a bowel movement in, then he may enter into there as many stones as his hand can grasp, as [even] if there will be stones left over from the night [of Shabbos, as he did not need to use all of them,] he will use them to clean with in the morning, and thus [these leftover stones] were not moved for no need.
The Reason: [Now,] even though other people also enter into this area to have bowel movements, and there is thus chance that they will use these leftover [stones] to clean themselves with, [nevertheless] this does not pose a problem, as [even if they do use the leftovers, the stones were still] in the end of the day moved for the use of others, which is not considered moving them for no need, as what difference does it make if one moves them for his own use or for the use of others.
Now even though that others can make their own effort to bring stones for themselves, nevertheless since it is possible that all these stones that he is entering will be needed to be used by him himself, [such as] if the others will not precede him in using the [stones] leftover from his current cleaning to clean themselves with, [it thus ends up] that he is now troubling [himself in bringing all these stones] for his own use.
How many stones may one bring with him if he does not have a designated bathroom area? However one who does not have a set area to use as a bathroom, meaning that at times he goes to one place and at times to another, then he [may only] enter with him the amount of stones [that would correspond to the size] of the head of a spice crusher and not anymore, as if [he will take more than this amount and] there will be leftovers from these [stones] and he will then go and use the bathroom elsewhere, it ends up that he [originally] moved these [leftover] stones for no need.
Stones that have already been used to wipe with: If it is recognizable on the stone that it had already previously been cleaned with [at least] once in the past, then it is permitted to enter it even if it is very large, or even if they are a lot more than a handful he may take all of them, as since they were [already] cleaned with and a stain from the cleaning is recognizable on them, they are [therefore] prepared and designated for this use, and are [thus] not considered Muktzah.
Stones that are designated to be used to wipe with: The same applies for stones which one designated to clean with from before Shabbos, even though he has never actually cleaned with them before, it is permitted to enter them into [any] bathroom, even if they are a large amount, as long as one permanently designated [these stones] for this use. However if they were only designated for one Shabbos, then this does not help [to remove its Muktzah status], as was explained in Chapters 259 [Halacha 5] and 308 [Halacha 53].
The law by a private bathroom used only by oneself: One who has a bathroom near his house which is not used by any other person is forbidden for him to enter into it stones on Shabbos, unless they are prepared and designated for this use.
The reason for this is: because one is expected to have prepared [the stones] there from before Shabbos, as he certainly had knowledge before Shabbos that he would need to use [the bathroom] on Shabbos, [and thus he should have already entered stones there] being that there is no other person which will enter the bathroom to use it for bowel movement.
However when other people, including even his household members, also use that bathroom for bowel movement, [the Sages] did not trouble him to need to prepare the stones there from before Shabbos based on a mere doubt [if he will even have a chance to use these stones on Shabbos, as] perhaps on Shabbos [when he goes to that bathroom] he will find it in use by someone else and will thus need to go elsewhere to have his bowel movement, as well [even if the bathroom is empty] perhaps they will [have preceded him and] cleaned with the stones that had been prepared by him [and he will thus not end up using the stones that he prepared. Therefore the Sages allowed him to bring stones with him on Shabbos].
Carrying stones to clean oneself with, within a Karmalis and Public domain:
First Opinion: There are opinions which say that [the Sages] only permitted carrying stones to clean oneself with inside a Private domain, or [to carry them] within a 4 cubit radius inside a Karmalis.
Second Opinion: [However] other opinions say that it is permitted to carry them even [more than] 4 cubits in a Karmalis, and [may even be carried] from a Karmalis into a private domain if one needs to do so.
Their reasoning is: because the [carrying in a] Karmalis prohibition is also only Rabbinical just as is the Muktzah prohibition, and [the Sages] thus also removed [the Karmalis prohibition] out of respect for humanity.
The Final Ruling: The ruling is that by a dispute regarding a Rabbinical prohibition one may follow the lenient opinion.
Removing the stones from mud:
If rain fell onto the stones [which were previously prepared to be used to clean with] and they sunk [into the mud as a result of the rain] then if they can still be seen [from above the mud, meaning that they have not completely sunk into the ground,] they are permitted to be taken to clean oneself with. This poses no problems of “Destroying” [the flooring of the outside where the stone was on], or of “Grinding” [the mud that the stone is removed from].
Using a stone that has mold growing on it:
The law: A stone which has grown [thick green] mold due to the grounds moisture is permitted to clean oneself with, and we do not [prohibit it due to a] suspicion that one may come to remove the mold from the stone [in the cleaning process], being that even if one does remove it, there is no prohibition involved [in doing so] as this is something done unintentionally.
The reason that this is not prohibited due to the prohibition to uproot a plant from the ground: Now, although the mold nurtures off the ground [and thus it should be prohibited to pick up the stone as by doing so it is like uprooting a plant from the ground, nevertheless] there is no prohibition of detaching and uprooting a plant from its source involved here by him lifting [the stone] up from the ground, as even [when the mold is] in the air they benefit and grow from the vapor of the grounds moisture, and are thus considered like they are still attached to the ground. Thus this lifting [of the stone] involves no Biblical prohibition, and is only [normally] Rabbinically prohibited to be lifted due to that it appears like one is uprooting as will be explained in chapter 336 [Halacha 12], and [thus] here [it is permitted as] out of respect for humanity [the sages] did not apply their decree.
Using other Muktzah materials to wipe oneself with
Using a piece of earth to clean oneself with:
One may not move a thick piece of earth to use to clean himself with, as it is not useable to clean with being that it breaks apart.
Cleaning oneself using pieces of pottery:
Rough earthenware: It is forbidden to use earthenware [which has a rough surface, to clean oneself with] even during the week as doing so is dangerous being that it can tear the membranes of the rectum. [Rather only smooth rocks and other smooth materials may be used.]
Using smooth earthenware during the week: [Furthermore] even smooth earthenware, such as a [broken] handle of a vessel which are smooth and do not tear the skin, one may not clean with it during the week out of fear that they have [had] a spell [cast upon them] . [However] it was already explained in chapter 3 [Kama Halacha 16] that in today’s times we no longer suspect for sorcery.
Using smooth earthenware on Shabbos rather than using a stone: However on Shabbos if one has [available] in front of him smooth earthenware and a stone he should clean himself with the earthenware, even during the times that they did have a suspicion of having a spell, being that [earthenware pieces] have a status of a vessel on them being that they are fit to be used to cover the mouth of vessels, and thus override cleaning oneself with the stone which is Muktzah, as [the Sages] only permitted one to clean himself with pebbles and stone if one has no other permitted [non-Muktzah] material available.
Using blades of grass over using stones:
One who had in front of him a stone and grass that is still attached to the ground, in which case both are Muktzah, then he should clean himself with the grass, [making sure] not to move them with his hands [but rather with his body], and should not clean himself with the stone which he will need to move with his hands [in order to use].
The reason it is allowed to clean oneself with grass attached to the ground: There is no prohibition in cleaning oneself with the grass of “[not to] use items attached to the ground”, as this was only forbidden by [using] trees however not by plants, as will be explained in chapter 336 [Halacha 4].
The law by dry grass: However the above only applies by moist grass, however dry grass is not used to clean with being that one who cleans himself with flammable material causes his lower membranes [of his rectum] to fall off. [Furthermore] even in today’s times that we are no longer careful against using flammable material to wipe with, as was explained in chapter 3 [Kama Halacha 16], [nevertheless] we [still] do not wipe with dry grass being that they are sharp and lacerate ones skin, as explained there [in Halacha 16]
May one use a tree to wipe if he has nothing else available?
If one does not have available in front of him even pebbles and stone to wipe himself with then there are opinions which permit using to clean even a tree that is attached [to the ground], as in a situation that the respect of a person [will be disgraced, the Sages] did not decree against using [trees] attached to the ground.
Using the leaves of the tree: Even if one needs to cleans himself with the leaves, it is allowed and we do no suspect that he may come to pull off [the leaf in the cleaning process], as [even if he does so] it is done unintentionally [and thus not prohibited].
Other Miscellaneous laws involved with a bowel movement on Shabbos
May one smoothen the stone on Shabbos?
One may not rub a stone to be used for cleaning, in order to smoothen it so that it not scratch his skin, in the same way that he does during the week, as this carries with it the prohibition of grinding. However one may rub it in an irregular manner such as [is done when] using the back of his hand.
Rubbing a stone on ones skin to treat constipation:
The law: One who feels the need to have a bowel movement but is constipated, in which case his treatment is to rub his rectum with a stone and the like, on Shabbos he may not rub it the same way he rubs it during the week, meaning by holding the stone within his entire hand and then rubs.
The reason for this is: because this form of rubbing tears membranes as although he does not intend to do this, nevertheless [it is forbidden on Shabbos] because it is inevitable to occur, as with certainty this form of rubbing tears off membranes. (And this rubbing was only permitted [with an irregularity on Shabbos or even regularly during the week] due to that constipation can lead to the Droken illness).
Practically how does one rub with it? Therefore it was required to be done with an irregularity, meaning to hold the stone with two fingers and rub gently.
Using a rod to rob with: Rubbing a [wooden] rod by ones rectum has the same law as rubbing a stone, that it should only be held with two fingers.
Carrying items that are inserted in one’s body into a public domain:
It is forbidden to go out [to a public domain or Karmalis] with this metal rod even if it is completely inserted into one’s body, as since one constantly enters it there in order to return and take it out, it is not nullified to the body, and is like carrying it in ones mouth and by ones elbow, which is Rabbinically forbidden. However an item which was swallowed into the body is permitted to go out with, such as to swallow a jewel or gold and go out with it into a public domain.
Making a bowel movement in a plowed field:
It is forbidden to make a bowel movement in a plowed field on Shabbos due to a decree that [one may come] to fill up gaps [that are in the field]. As he may take a stone from an earthy area to clean himself with and will then throw it onto a hole [in the field], and has thus smoothed the plowing [ground] which is an offshoot of [the Biblical prohibition] of plowing.
In someone else’s field: [Furthermore] if the field belongs to someone else, then it is forbidden to enter it even during the week, as he stumps on the plowing and ruins it.
Making oneself a toilet out from stones:
Large stones which are organized to create a seat with a hole which one sits on in fields by the area designated to be used as a bathroom, is permitted to be organized on Shabbos, being that [doing so] is a temporary structure that is not made to last, and a temporary structure is only prohibited to [be made] Rabbinically, and due to respect of humanity they did not apply their decree [in this case].
Nevertheless, to make a form of a tent with a roof is forbidden even though it is only a temporary tent.
 Seemingly the novelty here is that in addition to the regular Muktzah decree being removed, the Sages also did not refrain one from doing so even if it makes one place in a lot of effort on Shabbos and thus makes it seem more similar to a weekday, as explained in 308 Halacha 1 as being one of the reasons behind Muktzah.

 It seems from here that the explanation above that “one may trouble himself for others” does not suffice and that it is only because there is also a chance that he will come to use it, that he is allowed to do so. Vetzaruch Iyun
 This follows the explanation of the Rif and Rosh in the Gemara Shabbos 81a. However Rashi and Tosafus both learn that it is the amount of the leg of a spice crusher. The Michaber plainly mentions a “small spice crusher” without detailing its leg or its head.
 Mishneh Berurah 9, and so is implied from the Alter Rebbes wording of “The stone”
 Lit. “Their mark is recognizable”
 Mishneh Berurah 10
 Mishneh Berurah 11
 Mishneh Berurah 11
 Lit. herbs or grass

 Siddur Seder Netilah: “In the times of the Mishnah they would clean with small smooth stones”
 Lit. A back up of one’s feces.
 Mishneh Berurah 22
 Regarding the problem of Muktzah there are opinions that say that this is only referring to stones that have been designated before Shabbos to be used for this purpose. However others learn that even if not predestinated the Sages allowed one to move it. [Mishneh Berurah 312/25] [It seems from the Alter Rebbe like the latter as a) Why didn’t the Alter Rebbe mention the case is referring to designated stones, and b) if the stones were designated for this, then the structure made out from them is permanent not temporary.
