Q. As many read in your very important and informing answers, Horav Miller placed restrictions on where and how someone can daven with a minyan during these corona times. What happens if someone is paid for saying kaddish for a niftar and did so in a minyan that did not meet those requirements, did he comply with his obligation to say kaddish? If not, does he have to return the money?
How about if someone is standing while saying kaddish in someone’s backyard without asking permission, does he still comply with the kaddish?
A. While blowing with a shofar without permission from the owner may be questionable even bedieved (after the fact), if not for the concept that the mitzva is listening and not the blowing itself, also we assume that a person is pleased that someone else complies a mitzva with his property. (See Shulchan Aruch O.H. 586: 2, and Mishna Berura 9). Sefer Chasidim (771) rules that one who davens with a siddur that belongs to another without his permission, has to repeat his tefila; however, other Poskim disagree.
Horav Shlomo Miller’s Shlit’a opinion regarding our questions is that after the fact, he complies with the kaddish recital in both cases.
