- Q. Rabenu Shlit”a. I remember hearing that Poskim maintain that one should if possible be stringent and begin the fasting of Shiva Asar Betamuz already on the night before. Is that correct? Why?
If one has done so for more that three years and now finds it difficult does he have to do a Hatarat Nedarim (Release of Promises accepted by complying 3 times with a mitzva)?
A. On a regular Shiva Asar Betamuz, Mishna Berura (550: 6) writes that a Baal Nefesh should be stringent and keep the prohibitions already from the night before when possible, since it demonstrates the importance and value of the Taanis.
Horav Yaakov Hirschman Shlit'a opinion is that when one is not keeping it for a valid reason, as would be this year on Motzei Shabbos, no Hatoras Nedarim or release of promises is required. However some of our Rabanim disagree.
