Aruch HaShulchan is a work of halacha written by Rabbi Yechiel Michel Epstein. The work attempts to be a clear, organized summary of the sources for each chapter of the Shulchan Aruch and its commentaries, with special emphasis on the positions of the Jerusalem Talmud and Maimonides.
Title
The title "Aruch HaShulchan" is a clear allusion to the Shulchan Aruch, on which it draws, and to Aroch ha-Shulchan from. The Shulchan Aruch, authored in Safed by Yosef Karo in 1563, is a contemporary record of Sephardi laws and customs at the time and place of its making. Later, HaMapah, annotations for Ashkenazi Jews by Moses Isserles, was included in all editions of the Shulchan Aruch since 1578, embedded in the text and distinguished by a semi-cursive "Rashi script".
Structure
In Aruch HaShulchan, Epstein cites the source of each law as found in the Talmud and Maimonides, and states the legal decision as found in the Shulchan Aruch with the glosses of Isserles. When he deems it necessary, Epstein also mentions the views of other Rishonim, and especially Acharonim, occasionally disagreeing with the latter. The work follows the structure of the Tur and the Shulchan Aruch: A division into four large parts, subdivided into parallel chapters that match in all three works. These are further subdivided into paragraphs, but the latter do not match in the three works.
Method
Epstein tends to take a lenient view but decidedly without compromising in any form on the power and rule of Jewish law. When established custom is in conflict with theoretical halacha, Epstein tends to side with local custom, to a greater extent than is the case in works such as the Mishnah Berurah. Rabbi Moshe Feinstein once said that the decisions of the Aruch HaShulchan — who was a full-time rabbi — take precedence over many poseks who were not active rabbis. A rabbi takes into consideration more than just the abstract and black-and-white concepts of the law when rendering a legal opinion.
Similar works
The Aruch HaShulchan is often quoted alongside the Mishnah Berurah, a work partially composed earlier by Rabbi Yisrael Meir Kagan. The Aruch Hashulchan was composed and printed serially starting with Choshen Mishpat and the section on Orach Chayim published afterwards. Indeed, the Aruch HaShulchan refers in a number of places to the Mishnah Berurah. Due to the latter's popularity in the Haredi world, the Mishnah Berurah is often considered authoritative over Aruch HaShulchan by Haredi Jews. However, many people have famously held that the Aruch HaShulchan is more authoritative, since its author was the rabbi of a community, and since it was printed after the Mishnah Berurah. Also, Aruch HaShulchan has a much wider scope than the Mishnah Berurah.
Editions
The work was originally published during the author's lifetime in numerous small volumes that appeared from 5644-5653, beginning with Choshen Mishpat, at the beginning of which the author's introduction is found. Many volumes were reprinted posthumously by his daughter. Images of the first edition have been reprinted dozens of times to this day. These reprints usually appear in eight volumes, which mostly reflect the division of volumes in the Vilna edition of the Shulchan Aruch. The page numbering in the reprints still reflects the smaller volumes of the original printing. A ninth volume was published in 1992 by Rabbi Simcha Fishbane of Chicago, Illinois, who was given permission by the Israeli Bar-Ilan family, descendants of the author, to print 36 previously unpublished chapters on the laws of oaths. These chapters were found in manuscripts by the author's own hand, along with various sermons that were published together in the same volume. Another, longer section of Yoreh Deah, which consists of 60 sections on laws connected to idolatry, is still lost. The first completely new edition of Aruch HaShulchan appeared in 5766, by "Oz Vehadar" publishers in New Square, New York. This edition adds comparisons to rulings by the Mishnah Berurah in Orach Chaim. It originally did not contain the laws of oaths previously published by Fishbane, but they were subsequently added.
Aruch HaShulchan He'Atid
Epstein also wrote a similar work entitled Aruch HaShulchan he'Atid, a parallel work to Aruch HaShulchan summarising and analysing the laws that will apply in Messianic times. Some of the laws discussed, such as those relating to agriculture and farming, apply today for those living in the Land of Israel.
