Q. See question 3323 above. Someone is walking to his shul on Rosh Hashana or Yom Kippur and as he goes by an outdoor minyan or even a regular small minyan, they ask him to come in and complete the minyan; Does he have to join them?
A. Horav Shlomo Miller’s Shlit”’a opinion is that he should join until they can get someone else to replace him.
Rabbi A. Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit’a
