Zimmun: Difference between revisions

# According to some it’s crucial that the one who is listening understand the [[Birkat HaMazon]], while others are lenient and say that such is the minhag. <Ref>Mishna Brurah 193:5 </ref>

# If two people ate bread and a third person ate a [[kezayit]] of another food, some rishonim hold that they may not join together to make a zimmun, while other rishonim hold that they may join together for a zimmun. Many poskim hold that if the third person doesn't want to eat bread, one may join together for a zimmun. <Ref>S"A 197:3 writes that there are three opinions as to whether two who ate bread may join in a zimmun with a third person who didn't eat bread. The first opinion holds that one may not join together for a three person zimmun unless all three people ate bread. The second opinion holds that they may join together as long as the third person ate [[mezonot]]. The last opinion holds that as long as the third person ate anything, they may join together for a zimmun. S"A writes that in order to avoid a dispute one should not allow a third person who doesn't want to eat bread to join with the first two who are eating bread. The Mishna Brurah 197:22, however, writes that the minhag is in accordance with the last opinion allowing a zimmun of three as long as the third person ate something. Halacha Brurah 197:12 also writes that some are lenient. Chacham Ovadia Yosef in Sh"t Yachava Daat 4:13 (in the footnote) quotes the Knesset HaGedola who says that the minhag is to allow a zimmun of three as long as the third person ate something. He explains that the only reason S"A said one should avoid such a zimmun is because in his day people used to listen to the [[birkat hamazon]] of the leader of the zimmun, however, nowadays since everyone says the [[birkat hamazon]] to themselves such a zimmun is allowed. Mishna Brurah 197:20 notes that the third person must eat at least a [[kezayit]] in order to obligate a bracha achrona.</ref>

# If two people eat bread together and a third person ate a [[kezayit]] of another food, if the one who ate the other food said a [[Bracha Achrona]] without Zimmun, there is no obligation of Zimmun.<ref>Chaye Adam 48:1 writes that if two people eat bread together and a third person ate a [[kezayit]] of another food, if the one who ate the other food said a [[Bracha Achrona]] without Zimmun, there is no obligation of Zimmun since the one who ate food other than bread had a non-permanent meal to begin with and has already made a bracha achrona. Sefer Keysad Mezamnin (9:20, p. 122) concurs.</ref>
