Taanit 30a
תענית ל׳ א — ד"ה תַּנְיָא אִידַּךְ
Taanit 30a:9
A baraita discusses bathing restrictions on tishabav: bathing is prohibited in meals eaten specifically for the fast, but the dispute turns on whether bathing is permitted when eating meat is permitted—Rabbi Yishmael son of Rabbi Yosei rules that whenever meat-eating is permitted, bathing is also permitted, while other tannaim hold that bathing remains prohibited even in non-fast meals. The passage also teaches that all mourning restrictions apply on tishabav, including prohibitions on eating, drinking, anointing the body, wearing shoes, conjugal relations, and studying Torah and rabbinic texts.
תַּנְיָא אִידַּךְ: כֹּל שֶׁהוּא מִשּׁוּם תִּשְׁעָה בְּאָב — אָסוּר לֶאֱכוֹל בָּשָׂר וְאָסוּר לִשְׁתּוֹת יַיִן וְאָסוּר לִרְחוֹץ. כׇּל שֶׁאֵינוֹ מִשּׁוּם תִּשְׁעָה בְּאָב — מוּתָּר לֶאֱכוֹל בָּשָׂר וְלִשְׁתּוֹת יַיִן וְאָסוּר לִרְחוֹץ. רַבִּי יִשְׁמָעֵאל בְּרַבִּי יוֹסֵי אוֹמֵר מִשּׁוּם אָבִיו: כׇּל שָׁעָה שֶׁמּוּתָּר לֶאֱכוֹל בָּשָׂר — מוּתָּר לִרְחוֹץ. תָּנוּ רַבָּנַן: כׇּל מִצְוֹת הַנּוֹהֲגוֹת בְּאָבֵל — נוֹהֲגוֹת בְּתִשְׁעָה בְּאָב; אָסוּר בַּאֲכִילָה וּבִשְׁתִיָּה, וּבְסִיכָה, וּבִנְעִילַת הַסַּנְדָּל, וּבְתַשְׁמִישׁ הַמִּטָּה. וְאָסוּר לִקְרוֹת בַּתּוֹרָה בַּנְּבִיאִים וּבַכְּתוּבִים, וְלִשְׁנוֹת בַּמִּשְׁנָה בַּתַּלְמוּד וּבַמִּדְרָשׁ וּבָהֲלָכוֹת וּבָאַגָּדוֹת.
It is taught in another baraita: In any meal that is eaten due to the fast of the Ninth of Av, it is prohibited to eat meat; and it is prohibited to drink wine; and it is likewise prohibited to bathe in anticipation of the fast. However, in any meal that is not due to the Ninth of Av, i.e., one is eating the meal in order that he shouldn’t be hungry on the Ninth of Av, it is permitted to eat meat and to drink wine, but it is nevertheless prohibited to bathe at that time. Rabbi Yishmael, son of Rabbi Yosei, said in the name of his father: For the entire time that one is permitted to eat meat, he is likewise permitted to bathe. The Sages taught: All mitzvot practiced by a mourner are likewise practiced on the Ninth of Av: It is prohibited to engage in eating, and in drinking, and in smearing oil on one’s body, and in wearing shoes, and in conjugal relations. It is prohibited to read from the Torah, from the Prophets, and from the Writings, or to study from the Mishna, from the Gemara, and from midrash, and from collections of halakhot, and from collections of aggadot.
