Minchah on Shabbos Eve

HaYom Yom, entry for 19 Kislev. Indeed, there are those who hold that the contrary practice may have untoward results. The various opinions on this subject are cited in Shaarei Teshuvah on Orach Chayim 18. See also Pri Megadim, ad. loc., and the first rescension of the Responsa entitled Shem MiShimon (published in Satmar, 5632) on Orach Chayim, Sections 1 and 2. (From a letter of the Rebbe Shlita [reprinted in Likkutei Sichos, Vol. IX, p. 276, and in his Igrois Koidesh, Vol. XIX, p. 249].)

These three readings (Hodu, Pasach Eliyahu and Yedid Nefesh) likewise appear before the Minchah of erev Shabbos in Kol Yaakov, the Siddur compiled by R. Shabsai of Rashkov.

“The Baal Shem Tov instituted the practice of reciting Psalm 107 every erev Shabbos. (See Meor Einayim, end of Parshas Beshalach.) It is to be read before Minchah. (According to Ateres Zvi on Zohar II, 168b, this tradition was taught in the name of the Baal Shem Tov by his disciples.) It serves as a blessing of gratitude for the fact that one’s involvement in the workaday world during the foregoing week caused one no harm in body or in soul, neither spiritually nor materially. [Indeed,] the time for its recital is described in Shaar HaKollel (17:2) as ‘before Minchah, after one has finished with one’s weekday activities.’ The latter source also says that ‘one makes a point of reciting it together with the congregation,’ but I have not seen this in practice.” (Note of the Rebbe Shlita.)
