Taanit 26b-30a
Rabbi Yehuda obligates overturning the bed and sleeping on the floor on the eve of Tisha B'av as a mourning practice, but the Rabbis did not accept this ruling.
מִשֶּׁנִּכְנָס אָב מְמַעֲטִין בְּשִׂמְחָה. שַׁבָּת שֶׁחָל תִּשְׁעָה בְּאָב לִהְיוֹת בְּתוֹכָהּ אָסוּר מִלְּסַפֵּר וּמִלְּכַבֵּס, וּבַחֲמִישִׁי מוּתָּרִין מִפְּנֵי כְּבוֹד הַשַּׁבָּת. עֶרֶב תִּשְׁעָה בְּאָב לֹא יֹאכַל אָדָם שְׁנֵי תַבְשִׁילִין, לֹא יֹאכַל בָּשָׂר וְלֹא יִשְׁתֶּה יַיִן. רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר: יְשַׁנֶּה. רַבִּי יְהוּדָה מְחַיֵּיב בִּכְפִיַּית הַמִּטָּה, וְלֹא הוֹדוּ לוֹ חֲכָמִים.
Not only does one fast on the Ninth of Av, but from when the month of Av begins, one decreases acts of rejoicing. During the week in which the Ninth of Av occurs, it is prohibited to cut one’s hair and to launder clothes, but if the Ninth of Av occurs on a Friday, on Thursday these actions are permitted in deference to Shabbat. On the eve of the Ninth of Av a person may not eat two cooked dishes in one meal. Furthermore, one may neither eat meat nor drink wine. Rabban Shimon ben Gamliel says: One must adjust and decrease the amount he eats. Rabbi Yehuda obligates one to overturn the bed and sleep on the floor like one in a state of mourning, but the Rabbis did not agree with him.
