1. The washing of one’s hands after a bread meal before Birkat Hamazon is called Mayim Achronim. The Gemara finds support for this law from the pasuk “VeHayiteem Keoshim” and says it prevents Sedomite salt from getting into one’s eyes and blinding oneself. <ref>Brachot 53b, Chulin 105a-b</ref>
Mayim Achronim
2. Many Rishonim hold it applies in our times either because there is a concern of Sedomite salt even in our times, there’s an obligation of Kedusha, or it’s to have clean hands for Birkat HaMazon, (yet the obligation to wash applies even if one has clean hands without a mitzvah).
==The basics of the obligation==
3. On the other hand, some Rishonim say there is no obligation in our times because there’s no concern of Sedomite salt. So is the Minhag Ashkenazim, while Sephardim hold it’s an obligation.

Ravad(Brachot 6:2), Rashba(Chulin 105a), and Rashbetz(Brachot ch. 8) seems to hold that the purpose is to have clean hands for Birkat HaMazon. </ref>
# On the other hand, some Rishonim say there is no obligation in our times because there’s no concern of Sedomite salt. So is the Minhag Ashkenazim, while Sephardim hold it’s an obligation. <Ref> Tosfot (Brahcot 53b,Chulin 105a, Eiruvin 17b), Rama in Darkei Moshe 181:1, Levush 181:9 that so is Minhag Ashkenaz. Gra 181:12, Aruch HaShulchan 181:5, Mishna Brurah 181:22 hold it’s preferable for Ashkenazim to wash Mayim Achronim. </ref>
==Who is obligated?==
# Women are obligated in Mayim Achronim. <Ref> Torah Chaim Sofer 181:1, Shalmat Chaim 119, Halichot Olam vol 2 Shalach 1, against the Shevet HaLevi 4:23. </ref>
# Even if one didn’t touch the food with his hands, one is obligated in Mayim Achronim. <Ref> Halacha Brurah 181. If one has no water (up to 4 mil, which is less than 4 kilometers, on the way or 1 mil in the opposite direction) he should not touch the food when he eats. </ref>
# Some say one is obligated even if one didn’t even a meal but just touched salt. However the minhag is not to be stringent in this regard. <Ref> Chulin 105b is the source of the obligation and is brought down by the Rif (Brachot 8), so too the Talmidei Rabbenu Yonah, Raah, Michtam, Rashbez. The Rashba(torat bayit 6:1) is lenient. However nowadays no one is strict on this as the Tur and Shulchan Aruch left out this halacha. Pekudei Elazar 181, Halichot olam vol 2 shalach 1. </ref>
# Ashkenzim who don’t keep Mayim Achronim, if one’s hands are dirty and is concerned with cleanliness (Istanis) is obligated to clean his hands or wash them before Birkat HaMazon. <Ref> Shulchan Aruch 181:10, from Tosfot (Br 53b), Nemukei Yosef, Rosh 8:6, Mordechei Br 191, Aguda Br 8 and Tur. So too, if his ate or drank not in a bread meal and his hands are dirty he still must wash hands before the Bracha Achrona. Even not an Istanis who touched an unclean area or a covered area on the body must clean or wash his hands in any way before making a Bracha. Magan Avraham 181:10, Zechur leAvraham 40, Mishna Brurah 181:23, Kaf Chaim 181:9, Pri Megadim A”A 9. </ref>
==Interruptions between washing and making birkat hamazon==
# Some are strict not to talk even words of Torah. If he spoke it’s preferable that one wash again. <Ref> Kesef Mishna (Brachot 6:20) from Rashi and Rambam speech isn’t an interruption. The Magan Avraham 165:4 disagrees and is strict. So holds the Drisha 179:2, Eliyah Raba 179:1, Pri Migadim A”A 1, Chayey Adam, Zachur LeAvraham, Magan Giborim, Maharsham BeDaat Torah, Mishna Brurah 179:1. The Shulchan Aruch HaRav permits 2 or 3 words and the Aruch HaShulchan is lenient like the Kesef Mishna.  </ref>
# Some have the custom to say Shir HaMaalot, Lamnasech, or Avarechecha after Mayim Achronim since it’s a necessary element to Birkat HaMazon. <Ref> Kaf HaChaim 157:22 in name of the Arizal and Or Tzaddikim, Petach HaDvir 181:2, Chida(Simchat Haregel Seder Birkat HaMazon), Tziporen Shamir 5:61, Chesed LeAlafim 181:7,Ben Ish Chai Shalach 15, against the Aruch HaShulchan 181:9</ref>
# One can answer amen, kaddish, kedusha and barchu. <Ref> Tehilat LeDavid 181:2 says not to answer just like one juxtaposes Geula to Tefilah. However the Halacha Brurah 181:5 disagrees based on a Sfek Sfaka that maybe one can go like those who allow speech between mayim achronim and birkat hamazon and maybe one can go like those who say that one can answer devarim shbekedusha between Geula and Tefilah. Additionally it’s a mitzvah that’s fleeting. </ref>
# Preferably one shouldn’t wait or do actions unrelated to Brikat HaMazon more than 12 seconds; those who wait for everyone to wash their hands have what to rely on. <Ref> Bach 179, Pri Megadim 179;A”A 1, Mishna Brurah 179:1 in name of the derech hachaim that one should rewash, taz 181:3 says one can wait for 4 people to wash hands after you, so says the lavush 181:6, Olat tamid 181:4, magan Avraham 181:5, shulchan aruch harav 181:5 Mishna brurah 181:15, kaf hachaim 181:18, peulat tzaddik 3:71, yabea omer Y”D 2:1(11). The stringency of unrelated actions is sourced in the ritva hilchot brachot 3:17,6:21 and brought simlairly by kesef Mishna Brachot 6:20. </ref>
# In our time that everyone reads Birkat HaMazon one should try to have multiple vessels so everyone doesn’t have to wait long until Birkat HaMazon. <Ref> Biur Halacha D”H Min Hakatan. However, in earlier times, only one would say Birkat HaMazon. Accordingly, S”A 181:6 rules the one doing the birkat hamazon should be the first to wash but if there’s more than 5 people washing, then they begin washing from the least important person until there’s 5 people left and then the one doing birkat hamazon washes. </ref>
==Where to pour the water of Mayim Achronim==
# One may not wash over the ground because “ruach rah” hovers over it, rather one should wash into, in order of preference, a vessel, twigs or stones on the ground that absorb water, tiled flooring, ground not used like under the table and certainly a sink which has a drain. <Ref> S”A 181:2 from chulin 105a and many rishonim that hold like it. The Magan Avraham 181:2 in name of Chinuch that anything stopping the water from pouring on the ground, but the Rambam (brachot 6:16) seems to only allow a vessel. The Gra 181:4 explains S”A that initially we follow Rambam but if there’s no vessel available then we can rely on the Rashba (Torat Bayit 6:2) and Tur (181:2). Yabea Omer O”C 5:2 permits a sink by washing in the morning and all the more so for Mayim Achronim. Birur Halacha 181:8 concludes that one can pour it on the ground after one washed into the vessel.  </ref>
==Water that is fit for Mayim Achronim==
# One shouldn’t use scalding hot water, rather lukewarm water is permitted and it preferable to use cold water. Hot water that cooled is also permitted. <Ref> Tur and S”A 181:3 from Chulin 105a, rule leniently by lukewarm water, Kesef Mishna says Rambam (Brachot 6:16) allows it even initially. Magan Avraham 181:3 says in name of Maharshal that specifically cold water should be used. Mishna Brurah 181:7 says if one only has lukewarm, one shouldn’t be stringent. </ref>
# Bitter, dirty, or smelly water not fit for animals to drink is permitted. <Ref> Rashba Torat Bayit 6:2 says all water unfit for Mayim Rishonim is fit for Mayim Achronim. So is brought in the Bet Yosef (comments that so is implied by the Gemara and Posikim), Darkei Moshe, Orchot Chaim (Netilat Yadim 31), Kolbo (23) in name of Raavad, but the Riaz Netilat Yadim 8:20 is stringent. Many Achronim follow Rashba and Raavad such as Magan Avraham 181:7, Chaye Adam 46:2, Aruch Shulchan 181:6-7, Shulchan Aruch HaRav 181:8, Mishna Brurah 181:21, Kaf HaChaim 181:28. </ref>
# Spit is unfit; if nothing is available is better than nothing. <Ref> Peni Mabin O”C 38, Minchat Elazar 3:54, and Sherit Yehuda Blum 17 are stringent against the Torat Yekutiel Rosenberg O”C 6 who is lenient. </ref>
# If there’s no water, one can use other liquids but not wine, yet if nothing else is available then one should wash with wine. <Ref> Bet Yosef brings the Rabbenu BeChaye in Shulchan Shel Arba that allows all liquids and the Tur who doesn’t allow wine, S”A 181:9 holds leniently by wine, but many Achronim, such as the Levush 181:7, Atret Zekenim 181:2(2), Shulchan Aruch HaRav 181:8, Mishna Brurah 181:21 are strict like the Tur. </ref>
==Requirement of actually pouring the water==
# Dipping hands into water doesn’t suffice, but one who is lenient has what to rely on. <Ref> Magan Avraham 181:1, Shulchan Aruch HaRav 181:5, Mishna Brurah 181:3, Aruch Shulchan 181:7 agaisnt the Eliyah Rabba 181:9 who is lenient. Kaf HaChaim 181:9 says it’s effective for cleaning but not for the kabbalistic reasons and Zivchai Zedek 3:35 holds it’s not forbidden.  </ref>
# It’s permitted to wash under a running faucet. <ref> Raavad in Tamim Daim 66, Orchot Chiam Netilat Yadim 31, Kolbo 23, against Riaz Netilat Yadim 8:20 </ref>
==Amount needed for Mayim Achronim==
# Mayim Achronim doesn’t require a Reviat. Some opinions say one can use a Reviat and some opinions say not to use less. <Ref> Rashba Torah Bayit 6:2 that there’s no amount requirement, so says the Orchot Chaim Netilat Yadim 31, Kolbo 23 in name of Raavad. So holds the Achronim such as Levush 181:7, Atret Zekinim 181:1, Shulchan Aruch Harav 181:4,Kaf Hachaim 181:4. The Mishna Brurah 181:19 says the practice of Gra was to use a Reviat, against the Chida Simchat Regel (Seder Birkat Hamazon) and Ben Ish Chai Shalach 8 who say one should use less water. Accordingly, says the Birur Halacha 181:13 if one’s hands are dirty one should first wash with intent that it’s not for Mayim Achronim and then rewash with intent with less water. </ref>
# If one only has a Reviat of water one should use it for Mayim Rishonim and not Mayim Achronim. <Ref> Birur Halacha 181:4 from Bet Yosef 181:1, Eliyah Raba ibid, Mateh Yosef O”C 2:18(32) in name of Orchot Chaim, and Yad Aharon Siman 158  </ref>
==How the washing is done==
# One should wash up to the second knuckles and the first knuckle on the thumb, it’s preferable to be strict to wash the whole finger. <Ref> S”A 181:4 based on Rashba Torat Bayit 6:1 and Raavad against the Rabbenu Bechaye in Shulchan SHel Arba who requires the whole finger. Mishna Brurah 181:10 brings Talmedei Rabbenu Yonah that the thumb only up to the first knuckle. Biur Halacha D”H Ad Perek Sheni and Kaf HaChaim 181:17 say to be strict like the Arizal to wash the whole finger. </ref>
# There’s no Bracha for Mayim Achronim. <Ref> S”A 181:7. The Bet Yosef quotes the Ramah who hold that there is a Bracha and so holds some geonim and rishonim such as Yeraim 23, Shibolei Leket 149, Mordechai Brachot 191, Ravyah 1:145, Raavad Brachot 6:2. However the Bahag Brachot 6, Talmidei Rabbanu Yonah 40b, Rosh 8:6, Rambam Brachot 6:2 say not to make a Bracha.  </ref>
# One should face his fingers downward so that the dirt falls off. <Ref> S”A 181:5 based on Sotah 4b. Also brought down by Rambam (Brachot 6:16) and Tur. </ref>
# Only one washing is required, not two or three times. <Ref> Bet Yosef in name of Mordechai (Brachot 207), Mishna Brurah 181:21. </ref>
==Drying one's hands==
# From the strict law one doesn’t have to dry his hands, but it’s better to be strict to dry one’s hands. <Ref> S”A 181:8, Bet Yosef quotes Rashba in Torat Bayit 6:2 that one doesn’t need to dry one’s hands and the Rambam Brachot 6:20 who holds one needs to dry one’s hands. S”A brings both opinions but the Mishna Brurah 181:21 points out that in 173 S”A implies that he holds Mayim Achronim doesn’t need drying.  </ref>
==Practices related to Mayim Achronim==
# Some have the practice to say “Mayim Achronim Chovah (is obligatory)”. <Ref> Rav Chaim Palachi in Ruach Chaim 181:1, Ben Ish Chaim Shalch 7 says that it can count as a word of Torah during a meal.  </ref>
==If one forgot Mayim Achronim==
# If one forgot to wash Mayim Achronim before Birkat HaMazon or didn’t have water, must wash after Birkat HaMazon. <Ref> Chesed Alafim 181:8, Ben Ish Chai Shalch 11, Kaf Chaim 181:26, Mishna Brurah 181:2 against the Ometz Yozfa 155 who says not to wash because it degrades the sanctity of Birkat Hamazon.  </ref>

Mayim Achronim

The basics of the obligation

  1. The washing of one’s hands after a bread meal before Birkat Hamazon is called Mayim Achronim. The Gemara finds support for this law from the pasuk “VeHayiteem Keoshim” and says it prevents Sedomite salt from getting into one’s eyes and blinding oneself. [1]
  2. Many Rishonim hold it applies in our times either because there is a concern of Sedomite salt even in our times, there’s an obligation of Kedusha, or it’s to have clean hands for Birkat HaMazon, (yet the obligation to wash applies even if one has clean hands without a mitzvah). [2]
  3. On the other hand, some Rishonim say there is no obligation in our times because there’s no concern of Sedomite salt. So is the Minhag Ashkenazim, while Sephardim hold it’s an obligation. [3]

Who is obligated?

  1. Women are obligated in Mayim Achronim. [4]
  2. Even if one didn’t touch the food with his hands, one is obligated in Mayim Achronim. [5]

  4. Ashkenzim who don’t keep Mayim Achronim, if one’s hands are dirty and is concerned with cleanliness (Istanis) is obligated to clean his hands or wash them before Birkat HaMazon. [7]

Interruptions between washing and making birkat hamazon

  2. Some have the custom to say Shir HaMaalot, Lamnasech, or Avarechecha after Mayim Achronim since it’s a necessary element to Birkat HaMazon. [9]
  3. One can answer amen, kaddish, kedusha and barchu. [10]
  4. Preferably one shouldn’t wait or do actions unrelated to Brikat HaMazon more than 12 seconds; those who wait for everyone to wash their hands have what to rely on. [11]
  5. In our time that everyone reads Birkat HaMazon one should try to have multiple vessels so everyone doesn’t have to wait long until Birkat HaMazon. [12]

Where to pour the water of Mayim Achronim

  1. One may not wash over the ground because “ruach rah” hovers over it, rather one should wash into, in order of preference, a vessel, twigs or stones on the ground that absorb water, tiled flooring, ground not used like under the table and certainly a sink which has a drain. [13]

Water that is fit for Mayim Achronim

  1. One shouldn’t use scalding hot water, rather lukewarm water is permitted and it preferable to use cold water. Hot water that cooled is also permitted. [14]
  2. Bitter, dirty, or smelly water not fit for animals to drink is permitted. [15]
  3. Spit is unfit; if nothing is available is better than nothing. [16]

  1. Mayim Achronim doesn’t require a Reviat. Some opinions say one can use a Reviat and some opinions say not to use less. [20]
  2. If one only has a Reviat of water one should use it for Mayim Rishonim and not Mayim Achronim. [21]

How the washing is done

  1. One should wash up to the second knuckles and the first knuckle on the thumb, it’s preferable to be strict to wash the whole finger. [22]
  2. There’s no Bracha for Mayim Achronim. [23]
  3. One should face his fingers downward so that the dirt falls off. [24]
  4. Only one washing is required, not two or three times. [25]

Drying one's hands

  1. Some have the practice to say “Mayim Achronim Chovah (is obligatory)”. [27]

If one forgot Mayim Achronim

  1. If one forgot to wash Mayim Achronim before Birkat HaMazon or didn’t have water, must wash after Birkat HaMazon. [28]

Sources

  1. Brachot 53b, Chulin 105a-b
  2. Rambam(Brachot 6:3), Rabbeinu Yonah(Brachot 40b), Rif(Chulin 37b) hold that it applies because of danger. Ravad(Brachot 6:2), Rashba(Chulin 105a), and Rashbetz(Brachot ch. 8) seems to hold that the purpose is to have clean hands for Birkat HaMazon.
  3. Tosfot (Brahcot 53b,Chulin 105a, Eiruvin 17b), Rama in Darkei Moshe 181:1, Levush 181:9 that so is Minhag Ashkenaz. Gra 181:12, Aruch HaShulchan 181:5, Mishna Brurah 181:22 hold it’s preferable for Ashkenazim to wash Mayim Achronim.
  4. Torah Chaim Sofer 181:1, Shalmat Chaim 119, Halichot Olam vol 2 Shalach 1, against the Shevet HaLevi 4:23.
  5. Halacha Brurah 181. If one has no water (up to 4 mil, which is less than 4 kilometers, on the way or 1 mil in the opposite direction) he should not touch the food when he eats.
  6. Chulin 105b is the source of the obligation and is brought down by the Rif (Brachot 8), so too the Talmidei Rabbenu Yonah, Raah, Michtam, Rashbez. The Rashba(torat bayit 6:1) is lenient. However nowadays no one is strict on this as the Tur and Shulchan Aruch left out this halacha. Pekudei Elazar 181, Halichot olam vol 2 shalach 1.
  7. Shulchan Aruch 181:10, from Tosfot (Br 53b), Nemukei Yosef, Rosh 8:6, Mordechei Br 191, Aguda Br 8 and Tur. So too, if his ate or drank not in a bread meal and his hands are dirty he still must wash hands before the Bracha Achrona. Even not an Istanis who touched an unclean area or a covered area on the body must clean or wash his hands in any way before making a Bracha. Magan Avraham 181:10, Zechur leAvraham 40, Mishna Brurah 181:23, Kaf Chaim 181:9, Pri Megadim A”A 9.
  8. Kesef Mishna (Brachot 6:20) from Rashi and Rambam speech isn’t an interruption. The Magan Avraham 165:4 disagrees and is strict. So holds the Drisha 179:2, Eliyah Raba 179:1, Pri Migadim A”A 1, Chayey Adam, Zachur LeAvraham, Magan Giborim, Maharsham BeDaat Torah, Mishna Brurah 179:1. The Shulchan Aruch HaRav permits 2 or 3 words and the Aruch HaShulchan is lenient like the Kesef Mishna.
  9. Kaf HaChaim 157:22 in name of the Arizal and Or Tzaddikim, Petach HaDvir 181:2, Chida(Simchat Haregel Seder Birkat HaMazon), Tziporen Shamir 5:61, Chesed LeAlafim 181:7,Ben Ish Chai Shalach 15, against the Aruch HaShulchan 181:9.
  10. Tehilat LeDavid 181:2 says not to answer just like one juxtaposes Geula to Tefilah. However the Halacha Brurah 181:5 disagrees based on a Sfek Sfaka that maybe one can go like those who allow speech between mayim achronim and birkat hamazon and maybe one can go like those who say that one can answer devarim shbekedusha between Geula and Tefilah. Additionally it’s a mitzvah that’s fleeting.
  11. Bach 179, Pri Megadim 179;A”A 1, Mishna Brurah 179:1 in name of the derech hachaim that one should rewash, taz 181:3 says one can wait for 4 people to wash hands after you, so says the lavush 181:6, Olat tamid 181:4, magan Avraham 181:5, shulchan aruch harav 181:5 Mishna brurah 181:15, kaf hachaim 181:18, peulat tzaddik 3:71, yabea omer Y”D 2:1(11). The stringency of unrelated actions is sourced in the ritva hilchot brachot 3:17,6:21 and brought simlairly by kesef Mishna Brachot 6:20.
  12. Biur Halacha D”H Min Hakatan. However, in earlier times, only one would say Birkat HaMazon. Accordingly, S”A 181:6 rules the one doing the birkat hamazon should be the first to wash but if there’s more than 5 people washing, then they begin washing from the least important person until there’s 5 people left and then the one doing birkat hamazon washes.
  13. S”A 181:2 from chulin 105a and many rishonim that hold like it. The Magan Avraham 181:2 in name of Chinuch that anything stopping the water from pouring on the ground, but the Rambam (brachot 6:16) seems to only allow a vessel. The Gra 181:4 explains S”A that initially we follow Rambam but if there’s no vessel available then we can rely on the Rashba (Torat Bayit 6:2) and Tur (181:2). Yabea Omer O”C 5:2 permits a sink by washing in the morning and all the more so for Mayim Achronim. Birur Halacha 181:8 concludes that one can pour it on the ground after one washed into the vessel.
  14. Tur and S”A 181:3 from Chulin 105a, rule leniently by lukewarm water, Kesef Mishna says Rambam (Brachot 6:16) allows it even initially. Magan Avraham 181:3 says in name of Maharshal that specifically cold water should be used. Mishna Brurah 181:7 says if one only has lukewarm, one shouldn’t be stringent.
  15. Rashba Torat Bayit 6:2 says all water unfit for Mayim Rishonim is fit for Mayim Achronim. So is brought in the Bet Yosef (comments that so is implied by the Gemara and Posikim), Darkei Moshe, Orchot Chaim (Netilat Yadim 31), Kolbo (23) in name of Raavad, but the Riaz Netilat Yadim 8:20 is stringent. Many Achronim follow Rashba and Raavad such as Magan Avraham 181:7, Chaye Adam 46:2, Aruch Shulchan 181:6-7, Shulchan Aruch HaRav 181:8, Mishna Brurah 181:21, Kaf HaChaim 181:28.
  16. Peni Mabin O”C 38, Minchat Elazar 3:54, and Sherit Yehuda Blum 17 are stringent against the Torat Yekutiel Rosenberg O”C 6 who is lenient.
  17. Bet Yosef brings the Rabbenu BeChaye in Shulchan Shel Arba that allows all liquids and the Tur who doesn’t allow wine, S”A 181:9 holds leniently by wine, but many Achronim, such as the Levush 181:7, Atret Zekenim 181:2(2), Shulchan Aruch HaRav 181:8, Mishna Brurah 181:21 are strict like the Tur.
  18. Magan Avraham 181:1, Shulchan Aruch HaRav 181:5, Mishna Brurah 181:3, Aruch Shulchan 181:7 agaisnt the Eliyah Rabba 181:9 who is lenient. Kaf HaChaim 181:9 says it’s effective for cleaning but not for the kabbalistic reasons and Zivchai Zedek 3:35 holds it’s not forbidden.
  19. Raavad in Tamim Daim 66, Orchot Chiam Netilat Yadim 31, Kolbo 23, against Riaz Netilat Yadim 8:20
  20. Rashba Torah Bayit 6:2 that there’s no amount requirement, so says the Orchot Chaim Netilat Yadim 31, Kolbo 23 in name of Raavad. So holds the Achronim such as Levush 181:7, Atret Zekinim 181:1, Shulchan Aruch Harav 181:4,Kaf Hachaim 181:4. The Mishna Brurah 181:19 says the practice of Gra was to use a Reviat, against the Chida Simchat Regel (Seder Birkat Hamazon) and Ben Ish Chai Shalach 8 who say one should use less water. Accordingly, says the Birur Halacha 181:13 if one’s hands are dirty one should first wash with intent that it’s not for Mayim Achronim and then rewash with intent with less water.
  21. Birur Halacha 181:4 from Bet Yosef 181:1, Eliyah Raba ibid, Mateh Yosef O”C 2:18(32) in name of Orchot Chaim, and Yad Aharon Siman 158
  22. S”A 181:4 based on Rashba Torat Bayit 6:1 and Raavad against the Rabbenu Bechaye in Shulchan SHel Arba who requires the whole finger. Mishna Brurah 181:10 brings Talmedei Rabbenu Yonah that the thumb only up to the first knuckle. Biur Halacha D”H Ad Perek Sheni and Kaf HaChaim 181:17 say to be strict like the Arizal to wash the whole finger.
  23. S”A 181:7. The Bet Yosef quotes the Ramah who hold that there is a Bracha and so holds some geonim and rishonim such as Yeraim 23, Shibolei Leket 149, Mordechai Brachot 191, Ravyah 1:145, Raavad Brachot 6:2. However the Bahag Brachot 6, Talmidei Rabbanu Yonah 40b, Rosh 8:6, Rambam Brachot 6:2 say not to make a Bracha.
  24. S”A 181:5 based on Sotah 4b. Also brought down by Rambam (Brachot 6:16) and Tur.
  25. Bet Yosef in name of Mordechai (Brachot 207), Mishna Brurah 181:21.
  26. S”A 181:8, Bet Yosef quotes Rashba in Torat Bayit 6:2 that one doesn’t need to dry one’s hands and the Rambam Brachot 6:20 who holds one needs to dry one’s hands. S”A brings both opinions but the Mishna Brurah 181:21 points out that in 173 S”A implies that he holds Mayim Achronim doesn’t need drying.
  27. Rav Chaim Palachi in Ruach Chaim 181:1, Ben Ish Chaim Shalch 7 says that it can count as a word of Torah during a meal.
  28. Chesed Alafim 181:8, Ben Ish Chai Shalch 11, Kaf Chaim 181:26, Mishna Brurah 181:2 against the Ometz Yozfa 155 who says not to wash because it degrades the sanctity of Birkat Hamazon.
