Birchat Asher Yatzar
This is the approved revision of this page, as well as being the most recent.
After relieving oneself, one is obligated to say the bracha of Asher Yatzar. Chazal instituted that one should recite Asher Yatzar after relieving oneself. The bracha was instituted for a person to give praise to Hashem for creating man with great wisdom. 
- Any time one goes to the bathroom (urinating or moving one's bowels) one is obligated to say the bracha of Asher Yatzar.Asher Yatzar is said every time that one releases excrement, even if it was a minute amount. This applies to both solid and liquid waste.
- Even if he only went to check if he needed to relieve himself and then ended up going, such as before davening, one recites the bracha of Asher Yatzar.
- If no water is available to wash one's hands after relieving oneself, one should wipe one's hands on a piece of cloth or rub them against a hard surface such as a wall, and then recite Asher Yatzar. Later, when water becomes available, one should wash one's hands, but not repeat Asher Yatzar. 
Who is Obligated?
- Women are obligated to say Asher Yatzar as well.
- One should train his children to recite asher yatzar after using the bathroom.
- A person who still feels an urge to go to the bathroom again immediately after using the bathroom (diarrhea), should only say Asher Yatzar when he feels like he has cleared his bowels. One who feels the need to urinate immediately after urinating because of cold weather however, should recite asher yatzar anyway.
- One who urinates to get his urine tested should still say Asher Yatzar.
- Some poskim hold that you should not recite asher yatzar if there was blood in your excrement.
- Someone who passes urine through a catheter should recite Asher Yatzar. If they intermittently open it to be emptied, they can recite Asher Yatzar after each time they open it. If it is connected to a bag and left in, they can recite the bracha once a day in the morning. Some say that they can recite the bracha each time they feel that they have finished relieving themselves.
If one Didn't Recite it Immediately
- One should say Asher Yatzar immediately after using the bathroom.
- If one did not say it immediately, many Sephardic authorities hold that one can still say it for 72 minutes after going to the bathroom. Yet, other authorities say that one should not say it if 30 minutes past after going to the bathroom. However, many Ashkenazim poskim hold that there is no expiration for Asher Yatzar until he needs to go again.
- If one used the bathroom and forgot to say Asher Yatzar and then used the bathroom again, only one bracha should be recited to cover both uses. Additionally, the Aruch HaShulchan says that if one went to the bathroom but forgot to say Asher Yatzar and subsequently needed to relieve oneself again, one should first relieve oneself and then say one bracha of Asher Yatzar.
- If a person is unsure whether he recited Asher Yatzar or not, he should not recite it. One may however, think the beracha in his head without reciting the words.
Asher Yatzar vs. Other Berachot
- If one uses the bathroom and additionally needs to recite boreh nefashot on food that he ate, asher yatzar should be recited first.
- If one uses the bathroom and then needs to recite asher yatzar as well as birkat hamazon or al hamichya, birkat hamazon or al hamichya take precedence.
- One may recite asher yatzar after the beracha of hamapil if he uses the bathroom.
- If one left the bathroom and then heard thunder or saw lightning before reciting asher yatzar, he should recite the beracha on the thunder or lightning because the time for those passes quickly.
Asher Yatzar as Part of Birchot HaShachar
- In the morning, one who goes to the bathroom should make the bracha of Asher Yatzar. If one slept (more than 30 minutes) then, according to Ashkenazim, one should make the bracha of Asher Yatzar even if one did not go to the bathroom.  One must have slept in one's bed for at least a half hour after halachic midnight.
- If one woke in the middle of the night and went to the bathroom, one should make Asher Yatzar then and another Asher Yatzar in the morning. 
- Although elokai neshama is not a beracha hasemucha lachaverta, one should still make an effort to recite it immediately after asher yatzar.
Understanding Asher Yatzar
- Asher Yatzar is an interesting Bracha because it never directly addresses the topic that it is about. One reason for this type of formulation is because it is not respectful to talk about relieving oneself overtly 
- A lot of meaning is contained within Asher Yatzar, for example, as we have seen there are 45 words corresponding to the numerical value of the word "ADAM" 
- Numerous explanations are given for the word beChachma. Rashi  explains based on Bereishit Rabba 1:4 that it is referring to the fact that Hakadosh Baruch Hu can keep air inside a person even though we have so many holes in our bodies. Tosafot  explains that it refers to the fact that G-d created man's sustenance before he created him. The Maharsha  explains that it is referring to man, and that he was created as an intelligent being. The Lavush explains that it refers to the many different processes that are involved in man's digestion and excretion; including taking in the food, holding the food, absorbing the nutrients, and excreting the waste 
- Nekavim mainly refers to the mouth and the organ used for excretion but is written twice to include every orifice.
- Chalulim refers to the inner organs that they remain closed and don't break open.
- While Sephardim recite the yisatem before yipate'ach, Ashkenazim reverse that order and recite yipate'ach before yisatem.
- Although some authorities conclude the beracha rofeh cholei kol basar umafli laasot, this is not the common practice. Rather we conclude rofeh chol basar umafli laasot
How It Should Be Recited
- It is ideal to recite aloud and while in one place not doing anything else like drying one's hands.
- If a person thought the bracha in his mind and didn't enunciate the words with his lips even inaudibly, it is questionable if he fulfilled his obligation. However, he should not recite it again.

- Rosh (responsa 4:1) writes that even someone checking himself before a meal or davening if he needs to relieve himself, if he ends up going even a very small amount should recite Asher Yatzar. Bet Yosef OC 7:4 cites this Rosh. However, Rav Yair Bachrach in Makor Chaim 2:6 argues that since he didn't feel a need to relieve himself, he shouldn't recite a bracha of Ashar Yatzar. Yalkut Yosef Kitzur Shulchan Aruch 7:2 disagrees with the Makor Chaim in favor of the Rosh. Rav Asher Weiss (teshuva printed in Kuntres Mafli Lasot p. 37) also disagrees with the Makor Chaim. Piskei Teshuvot siman 7 fnt. 18 brings a proof that we don't follow the Mekor Chaim from the Minchat Yitzchak 6:38:3 who holds that Ashar Yatzar is recited even for incontinent urination. Nishmat Avraham siman 7 fnt. 9 quotes a letter from Rav Shlomo Zalman Auerbach where he questions the Mekor Chaim.

- Nishmat Avraham 7:1:2 quoting Har Tzvi 1:6 and Tzitz Eliezer 8:1:3. Rav Asher Weiss, however, in a teshuva printed at the end of Kuntres Mafli Lasot (p. 37), holds that Asher Yatzar is not recited since a person isn't relieving himself in the natural way. Nonetheless, they can recite Asher Yatzar each morning and have in mind to exempt all of the urinations.
- Nishmat Avraham 7:1:2 quotes Rav Shlomo Zalman Auerbach as suggesting reciting the bracha each day if it is left in and if not then reciting it each time it is opened. However, the Tzitz Eliezer 8:1 held the bracha is recited when the drops stop flowing. Yalkut Yosef Kitzur Shulchan Aruch 7:8 agrees. See Asher Yatzar for Catheter Insert on Dinonline.org.
- Mishna Brurah 7:6 writes that one should be careful to recite Netilat Yadayim immediately after coming out of the bathroom so that one doesn't need to go again before one says Asher Yatzar and be caught in a dispute if one should recite one or two brachot. See Mishna Brurah 165:2 that one shouldn't delay Asher Yatzar to say it after Netilat Yadayim if one went to the bathroom and then is having a meal since one was already obligated to make Asher Yatzar before Netilat Yadayim. See Birur Halacha v. 2 siman 7 p. 43 who quotes Shaar Shlomo Zarafia that one can only recite Asher Yatzar up to toch kdei dibbur and many who disagree with him.
- Yalkut Yosef Kitzur Shulchan Aruch 6:3 and Halacha Brurah 7:5 write that one has up to 72 minutes after having used the bathroom, as long as one doesn't need it again. Similarly, Sh"t Yechave Daat 4:5 says that if you only remembered after 72 minutes, one should say the bracha without Shem U'Malchut. On the other hand, Sh"t Be'er Moshe (2:10 2; 4:4 1) writes that one could say the bracha even up to an hour or two after using the restroom, as long as one does not have the urge to once again use the restroom.
- Ben Ish Chai (Vayetze #12) writes that one should not say Asher Yatzar 30 minutes after having gone to the bathroom. This is also the opinion of Kaf Hachayim 7:8 and Rav Ben Tzion Abba Shaul (Or LeTzion 2:1:19), but Rav Ovadia (Yabia Omer 9:OC:108:17) argues that had Rav Ben Tzion seen the Ritva in Pesachim, he would have agreed. Rivevot Efraim 8:2 writes that he originally ruled like Rav Ovadyah wrote in Yachave Daat (see previous note) that one may say it up until 72 minutes, however, after seeing many others who argued he said that one should be concerned for the opinion that says that one should not say it past 30 minutes after going to the bathroom. See also Rav Ovadyah in Yabia Omer 9:3 in his response to the author of the Revivot Efraim on this issue. See also Asher Yatzar... The Deadline by Rabbi Ari Enkin.
- Ritva Pesachim 46a s.v. viy writes that the expiration of Asher Yatzar is the amount of time it takes to walk 4 mil. He explains that even if a person goes to the bathroom in the morning he can say it in shul even though some time elapsed.
- Maharach Or Zaruah responsa n. 101 writes that the expiration of brachot achronot are connected to the time it takes to digest food since the bracha is connected to the enjoyment of having eaten food. However, Asher Yatzer isn't for that purpose. He doesn't know exact amount of time Asher Yatzar expires but it is certainly less than four hours.
- Pri Megadim E"A 7:1, Nesivos quoted by Pitchei Teshuva YD 341:5, Mishna Brurah 7:1. Yalkut Yosef (siman 6 fnt s.v. "Teshuva Al Divrei Hacholkim") proves that Levush 4:1 holds this way as well. He also quotes that this is the view of Birkat Hashem v. 4 p. 485.
- Shulchan Aruch 7:3 says that Asher Yatzar should be recited twice. However, Mishna Brurah 7:6 writes that most acharonim disagree and say that only one beracha should be recited. This is the opinion of the Bach Siman 7, Taz 7:2, Kitzur Shulchan Arukh 4:6, Kaf Hachayim 7:5, Yalkut Yosef Kitzur Shulchan Aruch 7:10, and Aruch HaShulchan 7:4.

- Rama 4:1 writes that one should make Asher Yatzar even if one did not go to the bathroom. Mishna Brurah 4:3 comments that this is only true if one slept at night. This is based on the pasuk: Emunatecha Rabba LeBekarim Chadashim, They are new every morning; great is your faithfulness (Eicha 3:23).

- Mishna Brurah 4:3 writes that it is preferable to make Asher Yatzar after one goes to the bathroom and not to push it off until Davening, because it is likely one will one go again and then not have made an Asher Yatzar for having gone the first time.

He warns that we should be extra careful about this since many people make this mistake often.
