6נִמְצֵאתָ אוֹמֵר שֶׁאִם נָתַן דְּמֵי הַמִּקָּח וְנֶאֱנַס קדֶם שֶׁיִּקָּחֶנּוּ. וְאָמַר לוֹ הַלּוֹקֵחַ תֵּן לִי מִקָּחִי אוֹ הַחְזֵר לִי אֶת מְעוֹתַי. וְאַף עַל פִּי שֶׁיֵּשׁ עֵדִים שֶׁאָבַד בְּאֹנֶס וְלֹא הָיָה בַּמּוֹכֵר כֹּחַ לְהַצִּילוֹ וְלֹא נִתְרַשֵּׁל בַּדָּבָר. הֲרֵי זֶה מַחְזִיר אֶת הַדָּמִים. שֶׁהֲרֵי תִּקְּנוּ חֲכָמִים מְשִׁיכָה. לְפִיכָךְ אִם הָיָה בֵּיתוֹ שֶׁל לוֹקֵחַ שֶׁיֵּשׁ בּוֹ הַחֵפֶץ שֶׁנִּמְכַּר מֻשְׂכָּר לַמּוֹכֵר לֹא תִּקְּנוּ לוֹ חֲכָמִים מְשִׁיכָה. שֶׁהֲרֵי הַמִּקָּח בִּרְשׁוּת הַלּוֹקֵחַ. וּמִשֶּׁנָּתַן אֶת הַדָּמִים נִקְנָה הַמִּקָּח וְאֵין אֶחָד מֵהֶן יָכוֹל לַחְזֹר בּוֹ:
Thus, if a purchaser paid for an article and it was destroyed by forces beyond his control before he took it, the purchaser may tell the seller: "Give me the article I purchased or return my money." Even though there are witnesses who saw that the article was destroyed by forces beyond control, the seller could not save it, and he was not lazy regarding the matter, the seller must return the money. For our Sages ordained that a kinyan is finalized through meshichah. For this reason, if the purchaser owned the house in which the article that was sold was held, and he was renting it to the seller, our Sages did not ordain that the article must be acquired through meshichah. For the article that was sold is in the domain of the purchaser. In this instance, once he pays the money, the sale is concluded, and neither can retract.
