5אִשְׁתּוֹ הַנְּשׂוּאָה אַף עַל פִּי שֶׁהוּא מִתְאַבֵּל עָלֶיהָ אֵינוֹ מִתְאַבֵּל עִמָּהּ עַל שְׁאָר קְרוֹבִים אֶלָּא עַל אָבִיהָ וְעַל אִמָּהּ מִשּׁוּם כְּבוֹד אִשְׁתּוֹ נוֹהֵג אֲבֵלוּת עֲלֵיהֶן בְּפָנֶיהָ. כֵּיצַד. מִי שֶׁמֵּת חָמִיו אוֹ חֲמוֹתוֹ כּוֹפֶה מִטָּתוֹ וְנוֹהֵג אֲבֵלוּת עִם אִשְׁתּוֹ בְּפָנֶיהָ אֲבָל לֹא שֶׁלֹּא בְּפָנֶיהָ. וְכֵן הָאִשָּׁה שֶׁמֵּת חָמִיהָ אוֹ חֲמוֹתָהּ נוֹהֶגֶת אֲבֵלוּת בְּפָנָיו. אֲבָל שְׁאָר קְרוֹבִים כְּגוֹן שֶׁמֵּת אֲחִי אִשְׁתּוֹ אוֹ בְּנָהּ וְהָאִשָּׁה שֶׁמֵּת אֲחִי בַּעְלָהּ אוֹ בְּנוֹ אֵין מִתְאַבְּלִין זֶה עַל זֶה. וְכֵן יֵרָאֶה לִי שֶׁאִם מֵתָה אֵשֶׁת קְרוֹבוֹ אוֹ בַּעַל קְרוֹבָתוֹ כְּגוֹן שֶׁמֵּתָה אֵשֶׁת בְּנוֹ אוֹ בַּעַל בִּתּוֹ אֵינוֹ חַיָּב לְהִתְאַבֵּל עֲלֵיהֶן. וְכֵן כָּל כַּיּוֹצֵא בָּזֶה:
With regard to a wife with whom one is married: Although one must mourn for her, he does not mourn together with her for her other relatives with the exception of her father and her mother. He observes the rites of mourning for them in her presence. When a man's father-in-law or mother-in-law dies, he overturns his bed and observes the mourning rites together with his wife within her presence, but not outside her presence. Similarly, when a woman's father-in-law or mother-in-law dies, she observes the rites of mourning in her husband's presence. With regard to other relatives, by contrast, e.g., the brother of one's wife or her son dies or when the brother of one's husband or his son dies, they do not observe the mourning rites in respect for each other. Similarly, it appears to me that if the wife of a person's relative dies or the husband of one of his relatives, e.g., the wife of one's son or the husband of one's daughter, one need not observe mourning rites for them. Similar concepts apply in all analogous situations.
