If Tishah beAv occurs on Sunday, or if it occurs on Shabbos and is deferred to Sunday, you may eat meat and drink wine on Shabbos.¹ 552:23) Even at the third meal, after Minchah, you may eat everything² that you are permitted to serve at this meal, even like the royal feast of King Solomon. but you should not have this meal in the company of friends.³ disagrees. He rules that if you are accustomed to eat in the company of friends every Shabbos, you may do so on this Shabbos as well, because, otherwise, it would be considered mourning in public, which is forbidden on Shabbos. (Ibid.) If a bris is to be held, the meal should be served before Minchah. But you are permitted to eat the third meal with your family, and you may say Birkas Hamazon with zimun. You must finish the meal, while it is still daytime,⁴ 552:24) because at twilight you are forbidden to eat, drink or wash. However, you should not take off your shoes until after Barechu is said. The Chazzan takes off his shoes before saying Vehu Rachum [He, the Merciful One], so that he should not get confused; but before [taking off his shoes] he should say: Baruch hamavdil bein kodesh lechol [Blessed is He Who separates between the holy and the secular], without mentioning Hashem's Name and Kingship [Hashem Elokeinu melech haolam].

If Tishah beAv occurs on Shabbos, you should be stringent and study only those subjects that you are allowed to study on *Tishah beAv;*⁵ cites Taz, who says that we can rely on his opinion, since many other Poskim are lenient and permit Torah study after midday, even on a weekday. therefore, we do not say Pirkei Avos. Reading the sidrah of the week twice and the Targum once, is permitted, before noon. If erev Tishah beAv occurs on Shabbos, it is forbidden to study in the afternoon, as on any other erev Tishah beAv.⁶ 553:9,10)

Before Maariv, we do not say Lamenatzei'ach bineginos, neither do we say Vihi no'am before Ve'atah Kadosh, for this was composed for the setting up of the Mishkan [Tabernacle] and now it is destroyed. Neither do we say Veyitein lecha (May Hashem grant you), nor do parents bless their children.

At dark, when you see the candlelight, you should say the berachah Borei me'orei ha'eish⁷. (Ibid. 556:1) [Who creates the lights of fire], and in the Shemoneh esrei we say: Ata chonantanu [You have favored us.] We do not say Havdalah over the cup of wine until the conclusion of Tishah beAv.⁸ 556:3) The introductory sentences beginnng with הִנֵה קֵל should not be said. But you should not say the berachah over the spices and over the light, even if you failed to say (the berachah over the light) on Shabbos night. You should caution your family not to do do any work before they say Hamavdil bein kodesh lechol [Who separates between the holy and the secular] without mentioning Hashem's Name and Kingship. If you forget to say Ata chonantanu, you need not repeat [the Shemoneh esrei], but you should finish the Shemoneh esrei, (as stated in Chapter 96, above), because you will say Havdalah over wine at the end of Tishah beAv. You should not taste any food before Havdalah, and if you find it necessary to do some work, you should first say: Hamavdil bein kodesh etc., without mentioning Hashem's Name and Kingship.
