Harchakot of Niddah

From Halachipedia

Basic Laws

  1. A man is required to separate from his wife during the time she is a niddah until she has a hefsek taharah, counts seven clean days and dips in a kosher mikveh. [1]
  2. This prohibition remains even if many years have passed since she became a niddah. It remains until she has a hefsek taharah, counts seven clean days, and dips in a kosher mikveh. [2]
  3. Because of the seriousness of separating from one's wife while she is a Nidda, Chazal enacted several fences to help the couple avoid situations that might bring them to transgress the prohibition of physical endearment during this period.[3]

Touching

  1. According to the opinion of many Rishonim, among them Maran HaShulchan Aruch, contact between a man and his wife who is a niddah is a biblical violation. Due to this fact, the Rabbis instituted many safeguards to prevent this. [4]
  2. It is forbidden for a man to touch his wife who is a niddah even in a slight way and even not in an affectionate way.[5] He may not even touch her clothing, nor she his, even if the clothing hangs loosely off the body and the person will not feel the touch. They should be also be careful that the clothing of one does not touch the clothing of the other. [6]
  3. A husband and wife are permitted to touch each other's clothing when the wife is a niddah while the clothes are not being worn by the spouse. [7] Similarly they are allowed to touch each other's bedding while their spouse is not lying on it. This applies even if the clothes or sheets are stained. A man is also permitted to remove his wife's sheet from her bed and put it on his own bed, even if the sheet is stained, as long as the sheet is not designated specifically for her use. [8]

Intimate Speech

  1. One should be careful not to act in an overly frivolous and light-headed manner when his wife is a niddah, nor should they speak of intimate matters, in order that they not come to transgress. [9]
  2. Some poskim permit playing games together when your wife is a niddah unless it leads to lightheartedness.[10]

Seclusion

  1. A man is permitted to be alone (yichud) in a room or house with his wife when she is a niddah. However, a man may not have yichud with any other woman, married or single.[11]
  2. If a bride is a niddah at her wedding, the bride and groom may not be alone together. The couple must have a constant chaperone. [12] Due to the sensitive nature of such situations and the severity of any misconduct, a competent Rabbi should be consulted for instruction.

Using the Same Utensils

Eating from Same Utensils

  1. It is forbidden for husband and wife to eat from the same plate or bowl.[13]
  2. Regarding eating from the same serving plate: if it is a food that one places the food on his own plate before eating (such as rice, meat, or salad), it would be permissible. If one puts the food directly into his mouth from the serving plate (such as nuts, seeds etc.), it would be forbidden to share that. [14]
  3. It is forbidden for a married woman to eat from the same bowl of food with other men other than her husband, father, brothers, and sons.[15]

Eating at the Table Together

  1. The husband and wife may eat on the same table if they make a sign between them to remind them that she is a niddah. They should place an item that normally isn't on the table between the two of them. [16] Additionally, they can sit in different seats than they normally would[17], use separate placemats[18], or sit on opposite ends of a very large table which can serve as a reminder.[19]
  2. According to many poskim the prohibition to eat together on the same table doesn't apply if there are others eating with them, even without a sign to remind them.[20] However, the prohibition to eat from the same plate still applies.[21]

Eating Each Other's Leftovers

  1. A husband cannot drink the leftovers of his wife's drink in front of her as this is considered a sign of closeness.[22] This is one directional, meaning the husband cannot drink from what remains in the wife's cup, but the wife is permitted to drink from what her husband leaves over.[23]
  2. The following are exceptions to this rule:
    1. If the drink is poured into another cup it would be permissible.[24]
    2. If someone else drank from the cup after his wife, the husband may drink.[25]
    3. If the wife drank from it but not in front of the husband, and the husband knows that she drank from it, one who is lenient has on whom to rely, but blessing will come to one who is strict.[26]
    4. If the husband doesn't know that his wife drank from it, he doesn't need to be told.[27]
    5. If the wife leaves the room, the husband can drink what remains in the cup since he is not drinking in front of her. [28]
  3. According to Sephardim, if a woman drank from a cup and left over part of it and they refilled it it would be permissible for the man to drink.[29] Ashkenazim don't accept this leniency.[30]
  4. For Sephardim, this prohibition only applies to drink and not food.[31] Ashkenazim, however, are strict for food as well.[32] Even for Ashkenazim, if the wife simply tasted the food like for Shabbat, the remaining food would not be called leftovers.[33]

Other Items

  1. A man is permitted to dry his face and hands with his wife's towel when she is a niddah. He also may use her toothbrush. There is no need to set aside a toothbrush or towel for her exclusive use when she is a niddah. [34]
  2. The couple may stand an umbrella together, as long as the umbrella is big enough to allow them both to be under it without touching. [35]
  3. A couple may read from the same book as long as they are careful not to touch each other.[36]

Sitting Together

  1. The husband may not sit on his wife's bed when she is a nidda, whether she is present or not, even if the linens have been changed to new ones. However, if it is a couch, where it is not used exclusively by her, the husband may lie on it even in front of his wife.[37] The wife may lie on her husband's bed as long as he isn't there, and may sit on his bed even if he is there[38]
  2. This is only about her bed. But the husband can sit in a chair, even if it is special for her even if it is a reclining chair.[39]
  3. If his wife is out of town when she is a nidda, the husband may lie in her bed.[40]
  4. When the wife is a nidda, the husband shouldn't use pillows or blankets that are used exclusively by her.[41]
  5. The couple may not lie together in one bed, even if it is large and wide. Even when they are on different beds, the beds should be separated. [42] This only applies if they are both in their beds.[43]
  6. They should also use separate blankets, even when the beds are separate.[44]

Traveling

  1. A couple may travel together in a private car or by public transportation, even when they sit next to each other as long as they are careful not to touch each other or each other's clothing.[45] However, some ashkenazim are strict unless the traveling is for a mitzva.[46] If the couple is using public transportation and they want to sit next to each other, he should sit on the outside and she should be near the window because he can be more careful and they should preferably place an item between them since it is difficult to otherwise avoid contact.Cite error: Closing </ref> missing for <ref> tag

Passing Items when a Woman is Niddah

  1. A man may not pass an item directly to his wife when she is a niddah, nor may he receive an item directly from her, lest they come to touch. In order to pass an object, they must place the item down on a table or chair for the spouse to pick up from there. [47]
  2. Even if the couple are in public and do not want others to know the woman is a niddah, they may not be lenient. They must place the item down and allow the spouse to pick it up, and not pass it directly. [48]
  3. One should be strict not to push or carry a large heavy item with one's wife who is a niddah.[49]
  4. A couple may not even pass a long object, such as a bench to each other when the woman is a niddah. In extenuating circumstances though, there is room for leniency, if they can be sure to avoid touching each other in the process. For example, if a couple lives on a high floor and there is no elevator, and they need to carry a baby stroller up and down stairs, and it cannot be carried by just one of them, the couple may be lenient and have the husband carry the bottom of the stroller and the wife the top, or vice versa, as long as they can be sure they will not touch in doing so. The law is the same with getting a stroller on or off the bus, or other similar situations. [50]
  5. A man is permitted to throw an object to his wife when she is a niddah, as long as it is not done in a lightheaded, frivolous, playful manner. One who is strict and refrains from doing so is praiseworthy, however. This only applies for Sepharadim. For Ashkenazim, the strict ruling is the law, and according to them, a man is not permitted to throw an object to his wife when she is a niddah. Even Ashkenazim may be lenient if the man throws the object into the air, and the wife catches it on the way down. [51]
  6. During the wedding ceremony, the groom may place the ring on the bride's finger, even if she is a niddah, he does not have to throw it to her. However, it is proper that he be as careful as possible to avoid touching her when giving her the ring. He should place it on the tip of her finger, and allow her to let it slide down her finger. [52]
  7. At a berit milah (bris or circumcision) if the mother wants to hand the baby to her husband who is the sandakthe person who holds the baby on his lap during the berit), it is the Sephardic custom to be lenient by having the baby placed on top of two pillows. The woman holds the baby by placing her hands underneath the bottom pillow, and the husband takes the baby from her by lifting the top pillow along with the baby, while the bottom pillow remains with the mother. (In this way they avoid touching). This custom has deep roots among the great Sephardic sages and the Ge'onim. The Ashkenazim though, are strict in this matter. A woman who just gave birth may not pass the baby directly to her husband who is the sandak. Rather, another man should take the baby from her and hand him over to the father. [53]
  8. When a woman is a niddah, a couple is permitted to pass a child to one another, as long as they will not touch, and as long as the child is able to go from one parent to the other on his own, since he is essentially carrying himself (nos'eh et asmo). However, one who is strict and refrains from doing so is praiseworthy. This is for Sepharadim. Ashkenazim though, who are strict regarding throwing an object to one another, should be particularly scrupulous in this matter as well. [54] However, even those who are lenient to pass a child when the wife is a niddah, should be strict if the child is extremely small, even if it can go from one to the other by itself (because its size increases the likelihood they will touch). Another case they should be strict is if the child is ill God forbid and too weak to go from one spouse to the other on its own. [55] Even when the baby is able to "carry" itself and go from one spouse to the other on its own, the couple should still pass the child to one another only when it is really necessary. For example, if the baby is crying and will suffer if the father does not take him from the mother. [56]
  9. Also, if the couple passes the child in a playful manner, that is prohibited, since doing so promotes intimacy. [57]
  10. It is preferable that a person be strict to not feed his baby while his wife who is a niddah is holding the baby. If necessary though, they may be lenient, if they are careful not to touch each other. [58]

Expressing Affection

  1. A husband may send jewelry or gifts to his wife or send her flowers when she is a Niddah as long as he isn't too effusive with his love for her lest they be drawn to do something prohibited.[59]

Looking at One's Wife

  1. A husband may enjoy his wife's look even when she is a nidda and we are not concerned that just looking at her will tempt him to transgress anything. However, he should avoid looking intentionally at the parts of the body that are usually covered to enjoy them[60]
  2. When a woman is a niddah the husband may not see areas of her body that are usually covered. The definition of what he usually sees uncovered depends on what she would normally wear at home with no one else besides her husband. It is permitted for him to see her hair uncovered when she is a niddah.[61]
  3. A husband may be present with his wife in the delivery room when his wife is giving birth if his presence helps calm her down but he should not look at the genital area. [62]
  4. A man may not look at the clothes of another woman who he knows even if she is not wearing them. However, he can look at his wife's clothes even when she is a nidda, and even if she is wearing them. [63]

Hearing her Voice

see Listening to Women Sing: Married Women

  1. The husband is likewise permitted to hear her play a musical instrument.[64]

Smelling her Perfume

  1. A husband should not intentionally smell his wife's perfume when she is wearing it, while she is a nidda. If he inadvertently smells it, it is not forbidden.[65]
  2. A woman may place a fragrance close to her husband so that he can smell it for the beracha of Besamim in Havdala.[66]
  3. A woman may smell her husband's cologne.[67]

Acts of Service

  1. Being a nidda doesn't prevent a woman from serving her husband as she does during her pure days besides for pouring a drink for him, making his bed, and pouring water for him to wash his face. Thus, a woman may cook, bake, set the table, etc. as she always does even when she is a nidda.[68]

Making the Bed

  1. A husband may not cover his wife with a blanket when she is a nidda.[69]
  2. It is prohibited for a woman to make her husband's bed in front of him. However, in the following circumstances it would be permitted:
    1. If she is only changing the blakets and pillows, that is permissible. It is only forbidden to change the sheets and bed covers.[70]
    2. If it is done not in front of him. Even if he is in the room, if he is looking away it would be permissible.[71]
    3. If she simply is making up the bed in the morning after he wakes up, that would be permitted. It is only forbidden if she is doing so when the husband is about to lie down.[72]
  3. All of these laws apply in both directions. Thus, the husband cannot make up his wife's bed, but all of the aforementioned leniencies would still apply.[73]

Pouring Water for the Husband to Wash With

  1. A woman may not pour water on her husband so he can wash his hands, feet, and face even if she is careful not to touch her husband since this expresses affection. [74]
  2. There is no prohibition for a woman to prepare water for her husband to wash his hand for netilat yedayim.[75]
  3. # All of these laws apply in both directions. Thus, the husband cannot prepare water for her to use for washing her hands, feet, and face, but all of the aforementioned leniencies would still apply.[76]

A Niddah Going to Shul and Cemeteries

  1. Ashkenazim have a minhag that woman don't look at the sefer torah when they are a niddah[77] and don't go to a cemetery when they are a niddah unless she would feel bad by not being able to go to the cemetery.[78]
  2. A woman who is a niddah may recite brachot and daven regularly.[79]

    • Tosfot Shabbat 13b s.v. biymey points out that from Rashi (Ketubot 61a s.v. michalfa) it sounds like there would have been leniencies of harchakot when a woman was counting her shiva nekiyim after she stopping seeing blood. Rabbenu Chananel (Ketubot 61a) also implies like rashi. However, Tosfot argues that this is totally incorrect since until the woman completed her shiva nekiyim and went to mikveh she is equally forbidden to her husband with a penalty of karet. The Rashba (Torat Habayit 4a), Raavad (Baalei Hanefesh p. 10), Rosh (Ketubot 5:24), and Rambam (Isurei Biyah 11:18) hold that really there is no difference between a women when she is seeing blood and when she is in her shiva nekiyim. The Rashba even argues that Rabbenu Chananel only meant if she went to mikveh twice but that it isn't proper to do so. See the Rivash 425 and Ramban Shabbat 13b who forbid this practice of going to mikveh twice.
  3. Taharat Yosef 3:3
  4. Torat HaTaharah p. 96
  5. The Gemara Shabbat 13b indicates from a conversation with Eliyahu Hanavi that it is forbidden for a man to touch his wife even in the slightest way when she is a niddah. See the Ravyah (Niddah no. 173) and Or Zaruah 1:360 who permit a man to touch his wife when she is a niddah in a non-affectionate way. All other rishonim reject this opinion. These rishonim include the Tosfot (Shabbat 13b s.v. biymey), Ramban (Hilchot Niddah 8:3), Rashba (Torat Habayit Hakatzar 4a), and Rambam (Isurei Biyah 11:18). Shulchan Aruch 195:2, therefore, forbids touching even not in an affectionate way.

    • The Avot D’rabbi Natan 2:1 writes that it is forbidden to speak unnecessary speech. The Tur 195:1 and Rashba (Torat Habayit 3b) explains that it is only referring to intimate speech which could lead to sin. Meiri Niddah 64a agreed. Shach 195:2 codifies the opinion of the Rashba.
  10. Mishmeret Hatahara (195:7 v. 2 p. 264) quotes Rav Elyashiv as saying that playing board games such as chess and checkers together with his wife when she’s a niddah. Chut Shani (Niddah p. 223) argues that playing chess or games is permitted unless it leads to lightheartedness.

  15. Rav Chaim Palagi (Kaf Hachaim 4:8) writes that it is forbidden for a married woman to eat from the same bowl with men other than her husband, father, brothers, and sons. His proof is the gemara Shabbat 13a which establishes a comparison between a niddah and a married woman for purposes of how we should be cautious not to violate any prohibition. Just like with a niddah it is forbidden to eat from the same bowl so too it is forbidden for other men to eat with a married woman from the same bowl.
  16. Shulchan Aruch YD 195:3, Taharat Yosef 3:16:2.
    • The Mishna Shabbat 11b establishes that it is forbidden for a man to eat with his wife when she is a zavah so that they don't come to sin.
    • The Rambam writes that it is forbidden for a man to eat on the same place as his wife when she is a niddah. However, the Raavad (Shaar Haperisha no. 1) argues that it is forbidden even on the same table. Ramban (Hilchot Niddah 8:3), Tur and Shulchan Aruch YD 195:3 follows the Raavad.
    • Does Heker Work? The Ravyah (Niddah no. 173) writes that it is forbidden for a man to eat with his wife when she is a niddah even if there is something unusual on the table to remind them. He writes that the rabbis of Narvona agreed with him. The Hagahot Mordechai (Shabbat no. 452) cites this opinion. The Gra YD 195:8 and 88:2 discusses these opinions and their proof from Shabbat 13a. However, the Raavad (Shaar Haperisha no. 1) holds that it is permitted for a husband to eat at the same table with a niddah as long as there is something to remind them such as only one eating on the tablecloth. The Rashba (Torat Habayit 3b), Tur and Shulchan Aruch 195:3 agree. See the Ramban (Hilchot Niddah 8:3) who allows using something unusual only if there's no other table available.
    • What this dispute might be based on? The Sidrei Tahara 195:7 explains that there's two concerns of eating at the same table. The first is that merely eating together is a symbol of endearment. The second is that by eating together at the table they might come to share food on the same plate as we find by eating milk and meat at the same table. He tries to show that this was a dispute between the Raah and Rashba and that the Rosh was concerned for both approaches. According to the first approach, the Sidrei Tahara concludes, that having something unusual on the table is ineffective since either way their eating together will still cause endearment. But according to the second approach as long as there is something unusual on the table they will remember not to share food.
  17. The Rabbenu Yerucham (cited by Bet Yosef 195:3) writes that it is permitted to eat at the same table as long as they sit in different places from where they usually sit. Kitzur Shulchan Aruch 153:6 and Taharat Habayit v. 2 p. 119 hold like Rabbenu Yerucham. Badei Hashulchan 195:37 writes that some are strict not to rely on this leniency since it isn't the minhag.
  18. Shulchan Aruch YD 195:3
  19. Shiurei Shevet Halevi 195:3:2, Taharat Habayit v. 2 p. 119, Taharat Yosef 3:16:3
  20. The Masat Binyamin 112 permitted a husband and wife to eat at the same table without anything unusual on it to remind them since the presence of other people will serve as a reminder to them. Chida in Shiurei Bracha 195:11, Rav Ovadia Yosef in Taharat Habayit v. 2 p. 110 and Taharat Yosef 3:17, and Rav Mordechai Eliyahu in Darkei Tahara p. 44 agree. Badei Hashulchan 195:34 writes that the Rashba (Mishmeret Habayit 3b) held that the presence of others doesn't help and the Raah (Bedek Habayit 3b) only permitted it if someone sat in between the husband and wife. However, Badei Hashulchan concludes, someone who is lenient has what to rely on because anyway the Rambam's opinion is that as long as they aren't eating on the same plate it is permitted. Rav Mordechai Willig (Niddah Shiur 125) was lenient like Rav Ovadia Yosef.
  21. Masat Binyamin 112 writes that even if others are at the same table the couple shouldn't eat from the same plate. Taharat Yosef 3:18 agrees. The Pitchei Teshuva 195:5 questions this since it is obviously forbidden to eat from the same plate in all cases because he will be eating her leftovers. Rav Moshe Feinstein in Igrot Moshe 1:92 answers that if the pieces of food are small and he isn't eating the pieces that she started to eat there is no concern of leftovers but still there is a concern of eating on the same plate.
  22. Shulchan Aruch 195:4, Taharat Yosef 3:19
  23. Rama 195:4 writes that she is permitted to drink his leftovers. Shach 195:5 explains that there's no concern for a wife to drink his leftovers since she's not going to instigate an aveirah with him. Taharat Yosef 3:20 agrees.

  30. Shach 195:9 writes that even though they refilled it, nonetheless, the leftovers are still there and forbidden for him to drink. Badei Hashulchan 195:59 agrees.
  31. The Orchot Chaim quoted by Bet Yosef 195:5 writes that while there is a dispute whether leftover drinks are permitted leftover food is certainly permitted. The Sidrei Tahara 195:8 explains that since it isn't usual to drink from the same cup if a man would drink his wife's leftover drink it would be a sign of endearment. However, since it is normal to eat someone's leftover food it isn't a sign of endearment. Rav Ovadia Yosef in Taharat Habayit v. 2 p. 125 and Taharat Yosef 3:21 agree.

    • Tosfot (Ketubot 61a s.v. biymey) writes that Rashi personally was careful not to pass anything to his wife when she was a niddah.
    Tosfot rejects any proof from the gemara for the opinion of Rashi. The Rashba (Torat Habayit Hakatzar 4a) and Rosh (Ketubot 5:24) are strict. Shulchan Aruch 195:2 codifies the practice of Rashi.
  48. Torat HaTaharah p. 98. Rav Moshe Feinstein in Igrot Moshe YD 2:77 writes that a couple may not be lenient on harchakot so that she's not embarrassed because harchakot aren't so embarrassing and also they are part of halacha and we shouldn't be embarrassed to keep halacha. Rav Mordechai Willig (Niddah Shiur 123, min. 15-20) disagreed and held that kavod habriyot could be used to permit harchakot in public when it is embarrassing and not in private.

  77. Shaarei Dura (Niddah no. 18) writes that a niddah shouldn't go into a shul. The Hagahot Maimoniyot (Tefillah 4:3) comments that the minhag was that a niddah wouldn't go into a shul. The Trumat Hadeshen (pesakim 132) permitted a niddah to go into shul on Yamim Noraim since otherwise they would feel bad not going to shul when everyone else is going. However, the Agur (no. 1388) writes that the minhag was that a niddah would go in a shul but just not look at the sefer torah when it is opened. The above discussion is all quoted in the Darkei Moshe YD 195:5. The Rama OC 88:1 quotes the dispute and concludes that the minhag was that a niddah shouldn't go into a shul. The Mishna Brurah 88:7 writes that the minhag today is to go into a shul but just not to look at the sefer torah when it is open.
  78. The Pitchei Teshuva YD 195:19 cites the Chamudei Daniel as saying that a niddah shouldn't go to a cemetery to daven. The Mishna Brurah 88:7 writes that a niddah shouldn't go to a cemetery. Shiurei Shevet Halevi 195 writes that a niddah shouldn't go to the cemetery because of a concern of mystical reason of tumah. However, it is permitted for her to go and stand 4 amot from the grave.
  79. The Shaarei Dura (no. 18) writes that a woman who is a niddah may not recite mention Hashem's name. The Darkei Moshe 195:5 quotes this as well as Rashi and others who hold that it is permitted. His conclusion is that the minhag is like the Shaarei Dura. Accordingly, Rama OC 88:1 writes that the minhag was that woman wouldn't daven when she was a niddah. However, the Bet Yosef 88:1, Magen Avraham 88:2, Pri Chadash 88:1, Gra (Maaseh Rav no. 58), and Mishna Brurah 88:7 write that there is no reason to be strict about this and in fact it is questionable how they can not recite brachot and daven when they are obligated to. In discussing teaching Torah to single girls the Tzitz Eliezer 10:8:4 writes that today we don't follow this Rama and the institution of the Bet Yakov seminaries is the proof.
