Moed Katan 24A

בעא מיניה רבי יוחנן משמואל: יש אבילות בשבת או אין אבילות בשבת? אמר ליה: אין אבילות בשבת.

R' Yoḥanan asked of Shmuel: Is there some mourning on Shabbat or is there no mourning on Shabbat at all? He said to him: There is no mourning on Shabbat at all.

יתבי רבנן קמיה דרב פפא וקאמרי משמיה דשמואל: אבל ששימש מטתו בימי אבלו ⁠— חייב מיתה. אמר ליה רב פפא: אסור אתמר, ומשמיה דרבי יוחנן אתמר,

The rabbis sat before Rav Pappa and said in the name of Shmuel: A mourner who had sex during his days of mourning is liable to receive the death penalty at the hand of Heaven. Rav Pappa said to them: It was said that sex are prohibited, but not that the offender is guilty of a capital crime. And the ruling was said in the name of R' Yoḥanan, and not in the name of Shmuel.

ואי שמיעא לכו משמיה דשמואל, הכי שמיע לכו: אמר רב תחליפא בר אבימי אמר שמואל: אבל שלא פרע ושלא פירם ⁠— חייב מיתה, שנאמר: ״ראשיכם אל תפרעו ובגדיכם לא תפרומו ולא תמותו וגו׳״, הא אחר שלא פרע ושלא פירם ⁠— חייב מיתה.

And if you heard a statement on this issue in the name of Shmuel, then you heard as follows: Rav Taḥlifa bar Avimi said that Shmuel said: A mourner who did not let his hair grow wild and did not rend his garments is liable to receive the death penalty at the hand of Heaven, as it is stated following the deaths of Nadab and Abihu concerning the surviving sons of Aaron: “Let not the hair of your heads go loose, neither rend your clothes, that you not die” (Leviticus 10:6). They were instructed not to mourn, so as not to interfere with the dedication of the Tabernacle. From here it may be deduced that any other mourner who did not let his hair grow wild or rend his clothes is liable to receive the death penalty.

אמר רפרם בר פפא, תנא באבל רבתי: אבל אסור לשמש מטתו בימי אבלו, ומעשה באחד ששימש מטתו בימי אבלו, ושמטו חזירים את גוייתו.

Rafram bar Pappa said: A Sage taught in Evel Rabbati, a separate tractate devoted to the halakhot of mourning: A mourner is prohibited from having sex during his days of mourning. There was an incident with one who had sex during his days of mourning and he was punished, for after his death pigs dragged away his corpse.
