Making Early Shabbat: Difference between revisions

#If it's necessary to do a Melacha and it's still early in the day before sunset, some say that may perform a Heiter Nederim, [[nullification]] of one's vow to accept [[Shabbat]] before 3 people, while others hold that the annulment isn't effective. <ref>Taz 263:3 and Levush hold that one may do Hatarat Nedarim to annul one's early acceptance of [[Shabbat]], while the Magen Avraham 263:31, Aruch HaShulchan 263:25, Mishna Brurah 263:5 hold that this annulment will not be effective to permit one to do Melacha. See Igrot Moshe 2:38 </ref>

#If someone made a mistake on Friday afternoon and prayed [[Arvit]] thinking that it was nighttime one has not fulfilled one’s obligation and would have to pray again. One would be permissible to do Melacha (activity forbidden on [[Shabbat]]) until one prays again, while others forbid. However, if a community made such a mistake they would not have to repeat [[Shmoneh Esrei]]. According to many one is permissible to do Melacha until one prays again while other to some it’s forbidden to do Melacha. <ref>Gemara [[Brachot]] 27b writes that on Friday afternoon someone who made a mistake and said [[Arvit]] early thinking it was nighttime according to Abaye he would have to pray again and it would be permissible to do Melacha. However, if it’s a community who made such a mistake Rebbe said that they do not have to repeat [[Shmoneh Esrei]] because of Tirech DeTzibbur. The Rosh 4:6, Tur, and S”A 263:14 rule that it’s permissible to do Melacha until they pray again, while the Magen Avraham 263:26 quotes many Rishonim (Or Zaruha, Rokeach, Raavan) who are strict and forbid Melacha since they don’t have to pray again. </ref>
