ב ב' צִבּוּרִין, אֶחָד שֶׁל חָמֵץ וְאֶחָד שֶׁל מַצָּה, וּב' בָּתִּים, אֶחָד בָּדוּק וְאֶחָד שֶׁאֵינוֹ בָּדוּק, וּבָאוּ שְׁנֵי עַכְבָּרִים זֶה נָטַל חָמֵץ וְזֶה נָטַל מַצָּה וְאֵין יָדוּעַ לְאֵיזֶה בַּיִת נִכְנַס זֶה שֶׁנָּטַל הֶחָמֵץ; וְכֵן שְׁנֵי בָּתִּים בְּדוּקִים וְצִבּוּר אֶחָד שֶׁל חָמֵץ וּבָא עַכְבָּר וְנָטַל וְאֵין יָדוּעַ לְאֵיזֶה בַּיִת נִכְנַס, אוֹ שֶׁיָּדַע שֶׁנִּכְנַס לְאֶחָד מֵהֶם וְנִכְנַס אַחֲרָיו וּבָדַק וְלֹא מָצָא כְּלוּם, אוֹ שֶׁבָּדַק קְצָת מֵהַבַּיִת וּמָצָא כִּכָּר, אֵינוֹ צָרִיךְ לַחֲזֹר וְלִבְדֹּק. כָּךְ הֵם דִּבְרֵי הַרַמְבַּ"ם, אֲבָל מַסְקָנַת הַפּוֹסְקִים אֵינוֹ כֵּן.
2 If there are two piles, one of chametz and one of matzah, and two houses, one that was checked and one that was not, and two mice came — one took chametz, and one took matzah — and we do not know which mouse entered which house: Or if both houses were checked and there was one pile of chametz, and a mouse came and took from it, and it is not known into which house it entered; Or even if we know it entered one of them, and someone entered after it and checked and found nothing, Or he checked part of the house and found a loaf, In all these cases, there is no need to recheck the house. (These are the words of the Rambam, but the conclusion of later halakhic authorities is not in agreement with him.)
