Q. I heard that some Sefarim rule that a Shofar is muktza on the night of Rosh Hashana and cannot be handled when you are not allowed to blow it. Is that correct?
A. Kovetz Halachos (Rosh Hashana 10: 11, p.126) quoting Horav Shmuel Kamemetzky Shlit’a debates the issue. He depends it on the Halacha whether the prohibition of muktza can apply to only a part of Shabbos or Yom Tov. He quotes Mishna Berura (331: 15) that it does, when it applies to the prohibition of muktza due to being a ‘Keli Shemelachto Leissur” or a utensil used for a prohibitive act. However, he remains in doubt.
Horav Shlomo Miller’s Shlit’a opinion is that it does not and the shofar is not muktza at all during the day or night of Rosh Hashana, when it does not coincide with Shabbos.
