תּוספֿתּא אויף אסתר 4:16

All who said [that after the first three fasts of Kislev had passed without rain, then for the next three fasts] they may eat and drink while it is still day, [but] they are forbidden from working, bathing, and anointing, from wearing shoes (lit., "sandals"), [and] from marital relations (Taan. 1:6), the day is forbidden for work but the night is permitted. From where is it derived that the day follows after the night? As it is said (Esther 4:16), "Go assemble all the Jews who are found in Shushan... [Do not eat or drink for three days -- night and day]." All those who said [that for the three fasts ordained after the 17th of Cheshvan (Taan. 1:4)], they may eat and drink once it gets dark, [and] they are permitted in working, bathing, and anointing, and in wearing shoes, [and] in marital relations, they may eat and drink until eastern [horizon] can be seen, the words for Rebbi. Rabbi Elazar b'Rabbi Shimon says, until the crow of the rooster. [But if] he slept and got up, he is forbidden immediately. All those who said they are forbidden from wearing shoes, one may put on shoes upon leaving a city, and remove them upon arriving to [another] city, and you may say the same regarding ostracism and mourning.
