I have a tradition from my parents to fast on Erev Shabbos Parshas Chukas, even though we don’t usually fast on Fridays. I usually fast the complete fast (Mashlim) until after Ma’ariv when I come back from Shul. Due to health issues we began this year making an early Shabbos, and daven Ma’ariv after Plag, not waiting until proper night begins. What should be done with the Ta’anis this Friday?

Not many are aware of this unusual Ta’anis and it is proper to explain. On question 2246-47 regarding the source for some fasting on Erev Shabbos Parshas Chukas and why would there be a fasting day on Erev Shabbos when we usually avoid it, we wrote: “Magen Avrohom (580: 9) and Mishna Berura (580: 16) quote the Tanya, that on Erev Shabbos Parshas Chukas, yechidim or some individuals accustom to fast. (Oz VeHadar Mishna Berura explains that it refers to the Arizal’s teachings (Shaar HaKavannos of Rav Chaim Vital, Drushei Tikkun Chatzos 1 and Pri Eitz Chaim, Shaar Tikkun Chatzo 3). The reason given, is that on that day (in the year 1242), twenty (or twenty four) wagons replete of Sefarim Gemaros. Talmudic literature including many works of the Baalei Tosafos and other priceless and irreplaceable manuscripts, (it predated the printing age), were burned in Paris by agents of the Church and King Louis IX. Magen Avrohom adds that it is “worthwhile for every Jew to cry for the burning of the Torah.” He then proceeds to tell of a customary annual fast specifically for this purpose, on Erev Shabbos Parshas Chukas. Additionally on year 5408 (Tach) – 1648, two great European communities were destroyed. The cause that it was instituted on the day of the week (Erev Shabbos) rather than on the day of the month, as all other days of fasting are, is because it was spiritually revealed to them that they should fast then, by using the Targum translation on “Zos Chukas Hatorah” Moed Lekol Chai (quoted by Nitei Gavriel – Bein Hamtzarim 1: 1: 3) mentions that on that Friday, as he remembers from his younger years in Izmir, people would refrain from leaving home and would try to arrange all that was needed for Shabbos on the prior Thursday. Even in his present day, he adds. people avoid traveling from city to city. He further quotes from Kisvei Hakodesh, the tradition to awake early and recite the Kina or lamentation of “Shaali Serufa Baesh.” We may add to the above that the Targum on “Zos Chukas Hatorah” is “Do gezeras ora’yso” meaning, this is the gezera (decree) to the Torah. There seems to be a different version on the Targum adding a vav or “VeDo” on day “Vav” or the sixth day, Friday, became gezeras ora’yso (Shibolei Haleket 263).The Torah is foretelling the future tragedies that will occur, and we now mourn the great loss to the Torah that happened on that day. There is no question that the burning of that collection of Seforim in Paris, at a time when every book was painstakingly written by hand and when many were original and irreplaceable, was a most terrible tragedy. It represented the destruction of generations of Jewish learning and work. It’s estimated that the wagons held about 10,000 sefarim and manuscripts. For how many Sages and Baalei Tosafos, it represented the extinction of a life’s work!” Horav Shlomo Miller’s Shlit’a opinion is that although you did not accept or kept this Ta’anis as a Neder or oath, it is proper to be Mattir Neder and perform prior to the fast day an act of Hattoras Nedorim or absolution of oaths and promises as printed in Sidurim.
