הלכות עירובין ב׳Eruvin 2

Halacha 1א׳

אַנְּשֵׁי הֶחָצֵר שֶׁעֵרְבוּ כֻּלָּן חוּץ מֵאֶחָד מֵהֶן שֶׁלֹּא עֵרֵב עִמָּהֶן בֵּין מֵזִיד בֵּין שׁוֹכֵחַ הֲרֵי זֶה אוֹסֵר עֲלֵיהֶן. וְאָסוּר לְכֻלָּן לְהוֹצִיא מִבָּתֵּיהֶן לֶחָצֵר אוֹ מֵחָצֵר לְבָתֵּיהֶן. בִּטֵּל לָהֶן זֶה שֶׁלֹּא עֵרֵב רְשׁוּת חֲצֵרוֹ בִּלְבַד הֲרֵי אֵלּוּ מֻתָּרִין לְהוֹצִיא וּלְהַכְנִיס מִבָּתֵּיהֶן לֶחָצֵר וּמֵחָצֵר לְבָתֵּיהֶן אֲבָל לְבֵיתוֹ אָסוּר. בִּטֵּל לָהֶן רְשׁוּת בֵּיתוֹ וּרְשׁוּת חֲצֵרוֹ הֲרֵי כֻּלָּם מֻתָּרִין. הֵן מִפְּנֵי שֶׁעֵרְבוּ וַהֲרֵי בִּטֵּל לָהֶן רְשׁוּת בֵּיתוֹ וַחֲצֵרוֹ. וְגַם הוּא מֻתָּר מִפְּנֵי שֶׁלֹּא נִשְׁאַר לוֹ רְשׁוּת וַהֲרֵי הוּא כְּאוֹרֵחַ אֶצְלָם וְהָאוֹרֵחַ אֵינוֹ אוֹסֵר:

[In a case wherein] all the residents of a courtyard made an eruv except for one of them who did not [participate] in the eruv with them: Such a one surely prohibits them [its use] — so it is forbidden for any of them to transport from their houses to the courtyard and from the courtyard to their houses. [If] this one that did not [participate] nullifies his rights only to the courtyard to them, they are surely permitted to transport out and in from their houses to the courtyard and from the courtyard to their houses — but it is forbidden to [do so, to and from] his house. [But if] he [also] nullified the rights to his house to them, they are surely all permitted — they, because they made an eruv and he nullified his rights to them over his house and [the] courtyard; and he is also permitted, since no rights remain to him. So he is surely like a guest; and a guest does not [create this] prohibition.

Halacha 2ב׳

הַמְבַטֵּל רְשׁוּתוֹ סְתָם רְשׁוּת חֲצֵרוֹ בִּטֵּל רְשׁוּת בֵּיתוֹ לֹא בִּטֵּל. וְהַמְבַטֵּל רְשׁוּתוֹ לִבְנֵי חָצֵר צָרִיךְ לְבַטֵּל לְכָל אֶחָד וְאֶחָד בְּפֵרוּשׁ וְאוֹמֵר רְשׁוּתִי מְבֻטֶּלֶת לְךָ וּלְךָ וּלְךָ. וְהַיּוֹרֵשׁ מְבַטֵּל רְשׁוּת אַף עַל פִּי שֶׁמֵּת מוֹרִישׁוֹ בְּשַׁבָּת שֶׁהַיּוֹרֵשׁ קָם תַּחַת מוֹרִישׁוֹ לְכָל דָּבָר. וּבִטּוּל רְשׁוּת בְּשַׁבָּת מֻתָּר לְכַתְּחִלָּה:

One who nullifies his rights without specification has nullified his rights to [the] courtyard, but not nullified his rights to his house. And one nullifies his rights to the residents of the courtyard needs to explicitly nullify [it] to each and every one and say, "My rights are nullified to you and to you and to you." And an inheritor may nullify his rights — even though his bequeather died on Shabbat. For the inheritor stands in the place of the one that bequeaths it to him for every matter; and nullification of rights is permissible at the outset [anytime] on Shabbat.

Halacha 3ג׳

בִּטְּלוּ אֵלּוּ הַמְעָרְבִין רְשׁוּתָן לְזֶה שֶׁלֹּא עֵרֵב. הוּא מֻתָּר שֶׁהֲרֵי נִשְׁאָר לְבַדּוֹ. וְהֵם אֲסוּרִין שֶׁלֹּא נִשְׁאָר לָהֶן רְשׁוּת. וְאֵין אוֹמְרִים יִהְיוּ כְּאוֹרְחִים אֶצְלוֹ שֶׁאֵין רַבִּים אוֹרְחִין אֵצֶל אֶחָד:

[If] these ones that made an eruv nullified their rights to this one that did not [participate] — he is permitted [in it], as he surely remained [as if] alone. But they are forbidden, as there are no rights left to them — and we do not say that they should be like guests, as the many are not guests with the one.
