משנה: אֵיזֶהוּ לְאַחַר זְמָן. כְּדֵי שֶׁתֵּרֵד מִן הַמִּיטָּה וְתָדִיחַ אֶת פְּנֶיהָ וְאַחַר כָּךְ מְטַמֵּא מֵעֵת לְעֵת וְאֵינָהּ מְטַמֵּא אֶת בּוֹעֲלָהּ. רִבִּי עֲקִיבָה אוֹמֵר מְטַמֵּא אֶת בּוֹעֲלָהּ. וּמוֹדִין חֲכָמִים לְרִבִּי עֲקִיבָה בָּרוֹאָה כֶתֶם שֶׁהִיא מְטַמֵּא אֶת בּוֹעֲלָהּ.
MISHNAH: What is “later”? That she should leave her bed and wipe her face. After that time she would retroactively make impure for 24 hours but does not make her sex partner impure; Rebbi Aqiba says, she makes her sex partner impure. The sages agree with Rebbi Aqiba that one who finds a stain makes her sex partner impure.
