Q. I also wonder, (see question 2782 above), when it rains the minyanim often meet wearing masks inside one of the houses, staying separately inside different adjoining rooms with open doors. Does this scenario qualify as a proper minyan?
A. As mentioned above, if the people in different rooms see each other and have a clear intention to be part of the minyan, Mishna Berura rules that in need one can be lenient. However, Horav Shlomo Miller's Shlit'a opinion is that regarding Chazaras Ha’shatz and Kerias Hatorah, one should be stringent.
Rabbi A. Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit'a.
