Q. Dear Rabbi. I’m a religious Canadian born and now an Israeli Army soldier soon to return after the army service to my family in Canada. Since my background is from a true Torah family, I have a number of Shaalot that I would much appreciate your answer with the background of great Rabanim you represent. Firstly I’m familiar with the new Mossad Chief Roman Gofman and I know well one of the two United Hatzalah medics who saved his life during the October 7 massacre. Are they supposed to celebrate a Seudat Hodaa soon and can they do it during the “Ben Hametzarim” time?
A. Poskim write that it is permitted to celebrate a birthday party during the Three Weeks until Rosh Chodesh Av. (See Halachipedya n.50.)
Tiferet Efraim pp. 481-482 quotes Rav Shmuel Kamenetsky (Kovetz Halachot pp. 15-18) who permitted going to a sports game even during the Nine Days and didn't consider the music to be a problem. Since the music isn't the main focus and is just incidental it is fine. However, he also quotes Rav Moshe Feinstein (Shemaytata Dmoshe 551:6) as holding that it is permitted during the Three Weeks but not the Nine Days. Rav Soloveitchik, as quoted there, held that going to a sports game is forbidden during the Three Weeks because it is a group activity, where being there with others is a simcha shel rabbim.
Some permit music at a meal for a Siyum Masechet of a Gemara (or the like) during the Three Weeks; Yachave Daat 1:45 writes that music is permitted for a seudat mitzvah including a siyum. Torat HaMoadim 5:4 and Yalkut Yosef (Moadim, 5748 edition, pg 554) also agree.
