426 Zimmun is required if all three participants ate bread. If only two participants ate bread, but a third person either eats a kezayit (about 1.5 ounces) of any food, or drinks a revi’it (about 4.4 ounces) of any beverage (other than water), the three should say zimmun | .[שו"ע או"ח, קצג ג; משניב, שם: כב 427 Even if the participants are not sitting together, as long as some of the partici- pants can see each other, they can join together in a zimmun [s-ayp או"ח, yw]. 428 If one of the three participants said Birkat HaMazon by himself, he may still join the other two to make a zimmun, but if two of them (or all three) said Birkat HaMazon by themselves, then no zimmun may be said קצד: א] nix .[שו"ע 429 Ata Sheva Berakhot meal, a special addition is made to the zimmun (page 1097) אבה"ע, סב: יג; ערוה"ש, שם: יח] pnw], and the Sheva Berakhot (page 109s) are said after Birkat HaMazon שם ו] yw]. 430 At the meal after a Brit Mila, a special zimmun (page 1075) is said, and a series of prayers (pages 1077-1079) is added before the end of Birkat HaMazon. 431 At a meal in a house of mourning, a special addition is made to the zimmun, and the third and fourth blessings are changed (page 1123) .[ערוה"ש יו"ד, שעט א-ב]

417 One should not remove bread from the table until after Birkat HaMazon is said .[שו"ע או"ח קפ א] 418 Prior to saying Birkat HaMazon, one should wash the grime off one’s fingers with mayim aharonim או"ח, קפא א] yw]. Some have the custom not to wash with mayim aharonim, because the original reasons for the practice no longer apply ] שם, י; משמיב שם, כב [, but a fastidious person who washes after a meal should wash with mayim aharonim before Birkat HaMazon [nw שו"ע: [ 419 Women are obligated to say Birkat HaMazon [שו"ע או"ח, קפו: א] 420 Birkat HaMazon should be said where one ate. If one forgot to say Birkat HaMazon and went elsewhere, one should return to the site of the meal to say Birkat HaMazon. If one cannot return to the site of the meal, one is permitted to say Birkat HaMazon as soon as one remembers to do so שו"ע ורמ"א או"ח, קפד:] how .[א; משניב, 421 If one forgets to say Birkat HaMazon at the end of the meal, it must be said afterward, so long as one does not feel hungry או"ח, קפד: ד] yw]. If one wants to eat again, one may wash hands and say המוציא again; the subsequent Birkat HaMazon then covers the first meal as well ] קעח: ב nix רמ"א [. 422 On Hanukka or Purim, one adds mp3 ועל (page 1035) to the second blessing. If one forgets וְעַל הַנַּפִּים one is not required to repeat Birkat HaMazon [nx yw תרפב: א; שו"ע ורמ"א או"ח, תרצה: ג 423 On Shabbat, one adds רְצָה (page 1037) to the third blessing. On Rosh Hodesh, Yom Tov and Hol HaMo'ed, one adds יעלה ויבוא ( page 1039) to the third blessing; if it is also Shabbat, one says my, then x13 74x». If one forgets to say the required addition on Shabbat or Yom Tov, one repeats the entire Birkat HaMazon. Al- ternatively, if one remembers before beginning the fourth blessing, one may say a special blessing in honor of Shabbat or the appropriate Yom Tov ] שו"ע או"ה .[קפח: ה-ו If one forgets the required addition on Rosh Hodesh or Hol HaMo'ed, one is not required to repeat Birkat HaMazon [שס:ו] 424 Ifone started eating while it was Shabbat, Rosh Hodesh or other days on which additions to Birkat HaMazon are said, and continued the meal after sunset, one still says the additions to Birkat HaMazon [שם:י] (see laws 422-423 above). 425 If three adult males eat a meal together, they are required to preface Birkat HaMazon with zimmun (page 1031). If women are present, they are required to join in the zimmun as well. Three adult females may also form a zimmun, but are not obligated to do so. If ten or more males are present, the word wbx is added to the formula [x קצב: nx yw].
