הַמְקַדֵשׁ בְּדָבָר שֶׁהוּא אָסוּר בַּהֲנָאָה כְּגוֹן חָמֵץ בְּפֶסַח אוֹ בָּשָׂר בְּחָלָב וְכַיּוֹצֵא בָּהֶן מִשְּׁאָר אִסּוּרֵי הֲנָאָה אֵינָהּ מְקֻדֶּשֶׁת. וַאֲפִלּוּ הָיָה אָסוּר בַּהֲנָאָה מִדִּבְרֵיהֶם כְּגוֹן חָמֵץ בְּשָׁעָה שִׁשִּׁית מִיּוֹם אַרְבָּעָה עָשָׂר אֵינָהּ מְקֻדֶּשֶׁת:
When a man consecrates a woman with an object from which it is forbidden to derive benefit - e.g., a mixture of milk and meat, chametz on Pesach, or other similar objects from which it is prohibited to derive benefit - she is not consecrated. [This ruling applies] even if the prohibition against deriving benefit from the object is merely Rabbinic in origin - e.g., chametz during the sixth hour on the fourteenth of Nisan.
