SHABBOS

First day of Rosh Hashanah, 1 Tishrei, 5787

• We do not blow the shofar on Shabbos.

  The purpose of blowing shofar is to draw Hashem's pleasure toward the world, so that He agrees to rule over it and grant it sustenance for another year. On Shabbos, Hashem's pleasure from His creations emanates on its own—this is the deeper reason why we do not blow shofar on Shabbos.

  The Alter Rebbe

  A shofar is muktzah on Shabbos.

• Shacharis

  During davening and Shemoneh Esrei, add the pieces for Shabbos.

  During chazaras hashatz, say the piyutim for the first day of Rosh Hashanah, while omitting parts not said on Shabbos.

  In the early years, the Rebbe would stand whenever the aron kodesh was opened (during chazaras hashatz and so on). However, in later years, the Rebbe would often remain seated.

  Similarly there were years when the Rebbe would stand at the conclusion of the berachos during chazaras hashatz, and there were years when the Rebbe would remain seated.

• Krias Hatorah

  Even on Shabbos, when the aron kodesh is opened, say Vayehi Binsoa Ha'aron, the Yud-Gimmel Midos Harachamim (three times), the Ribono Shel Olam for the Yamim Nora'im and Berich Shemei.

  Two Sifrei Torah are removed from the aron kodesh. From the first Sefer Torah, seven aliyos are read in the kriah of VaHashem pakad es Sarah (Bereishis 21:1-34). The second Sefer Torah is then placed next to the first one, and Chatzi Kaddish is recited. This is followed by hagbah and gelilah of the first Sefer Torah.

  With the exception of Maftir, the Torah is read with the special tune of the Yamim Nora'im.

  From the second Sefer Torah, Uvachodesh Hashvi'i is read for Maftir (Bamidbar 29:1-6). This is followed by hagbah and gelilah of the second Sefer Torah, after which the haftorah is read (I Shmuel 1:1–2:10).

• Musaf

  During chazaras hashatz, say the piyutim for the first day of Rosh Hashanah, while omitting parts not said on Shabbos.

  At the point when shofar is blown when Rosh Hashanah is not on Shabbos, say Hayom Haras Olam, but not Areshes Sefaseinu.

  If the floor of the shul is made of marble or stone, put down a towel or other separation before bowing during Aleinu.

  The Kohanim duchen during chazaras hashatz. For details about Birchas Kohanim, see below, "Hosafos.”

• Rest of the Day

  For Kiddush, say all the usual pieces said on a Shabbos day, but quietly.

  Then, say Tik'u and Borei Peri Hagafen in a regular voice.

  When bentching, add Retzei and Yaaleh Viyavo, inserting the words beyom hazikaron hazeh, beyom tov mikra kodesh hazeh. Additionally, say the Harachaman for Yom Tov, followed by the Harachaman for Rosh Hashanah, in addition to the Harachaman for Shabbos. See below, "Hosafos," for the halachos that apply if you forgot to say Yaaleh Viyavo.

  It is customary to refrain from sleeping (or wasting time) during the day of Rosh Hashanah.

  The Torah is read during Minchah.

  Tashlich is not performed on Shabbos.

  It is forbidden to prepare today for tomorrow.
