May a Torah scholar annul (heter nedarim) a person's vow on Shabbat when the vow is not relevant to Shabbat needs, and the vow could have been annulled before Shabbat?
Synopsis
The Mechaber rules that a Torah scholar may annul vows on Shabbat only if the vow pertains to Shabbat needs (e.g., a vow not to eat or drink). Vows unrelated to Shabbat may not be annulled, since they can be annulled after Shabbat. The Mishnah Berurah adds that vows related to a mitzvah may also be annulled even if not Shabbat-specific.
