סימן צד סעיף כו
עִיר הַמְתֻקֶּנֶת בְּעֵרוּבִין וְנִתְקַלְקֵל הָעֵרוּב בַּשַׁבָּת, אָז כָּל הַחֲצֵרוֹת שֶׁהֵן כְּתִקּוּנָן וְאֵין בָּהֶן פִּרְצָה הָאוֹסֶרֶת (עַיֵן לְעֵיל סִימָן פ"ב סָעִיף ד' ה'), אֲפִלּוּ יֵשׁ בֶּחָצֵר כַּמָּה בָּתִּים, מֻתָּרִין לְטַלְטֵל שָׁם כָּל אוֹתוֹ הַשַׁבָּת. וְאַף עַל פִּי שֶׁעֵרוּב הַחֲצֵרוֹת הוּא בִּרְשׁוּת אַחֶרֶת שֶׁנֶּחְלְקָה עַתָּה מֵחָצֵר זֹה, מִכָּל מָקוֹם מֻתָּר, מִשּׁוּם דִּלְעִנְיָן זֶה אָמְרֵינָן, שַׁבָּת כֵּיוָן דְּהֻתְּרָה, הֻתְּרָה. וְכֵיוָן שֶׁיֵּשׁ חֲשָׁשׁ גָּדוֹל שֶׁלֹּא יִכָּשְׁלוּ רַבִּים לַשֵּׂאת גַּם בְּמָקוֹם שֶׁנֶּאֱסַר, כֵּיוָן שֶׁהֻרְגְּלוּ בְּהֶתֵּר, עַל כֵּן אִם אֶפְשָׁר לְתַקְּנוֹ עַל יְדֵי אֵינוֹ יְהוּדִי, מֻתָּר. וְאִם נִקְרַע הַחֶבֶל שֶׁבְּצורַת הַפֶּתַח וְאֶפְשָׁר שֶׁהָאֵינוֹ יְהוּדִי יְתַקְּנוֹ בַעֲנִיבָה אוֹ בְּקֶשֶׁר אֶחָד וַעֲנִיבָה עַל גַּבָּיו, מַה טּוֹב.
If a city-wide eiruv became defective on Shabbos, the residents of every courtyard that is properly [surrounded with partitions] in which there is no break [large enough] to make [carrying there] forbidden,68That is if the whole of a wall is broken down or if the majority of all the walls is broken down or if there is a breach of more than ten amos width in one wall. These are general rules, but a posek must be consulted every time these halachos are involved.—even if that courtyard contains many houses—are permitted to carry there the entire Shabbos. Even if the eiruv is deposited in another premise which is now separated from this courtyard, nevertheless, they are permitted [to carry], because regarding this, we say, "Once it was permitted on that Shabbos, it continues to be permitted."69This is true only if it is open to another private domain, but if it is open to a public domain or karmelis, you may not continue to carry in your court. [see Shulchan Aruch 374: 2] 70See Shulchan Aruch 365: 8. See Shulchan Aruch 374: 1 and Bi’ur Halachah at length. However, since there is strong reason to be concerned that many people will fall into error and carry [by mistake], even in places where it is now forbidden to do so, since they are accustomed to carrying legally; therefore, if it is possible to have it repaired by a non-Jew, it may be done.71Even if it requires doing a melachah de’oraisa (as is evident from the Kitzur Shulchan Aruch). [Chayei Adam 62: 11, and Mishnah Berurah 276: 25, Rema 276] This ruling is based on the Ittur who permits this because it is a mitzvah involving the public. [Machatzis Hashekel 365] If the string of the "form of the door" was torn, and it is possible for a non-Jew to repair it with a loop, or by making one knot and a loop over it, so much the better.
