Women and Mezuman

Hi,

When three men eat a meal together, they are obligated to participate in a "mezuman" for the blessing after meals. [Women are not obligated to create their own mezuman, but they may if there are three women.]

Where women eat with a group of three men, they are obligated to respond to the mezuman, and the men are prohibited from performing the mezuman without inviting them to participate.

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 5:9:10)

Have a great day,
Mordechai
