הלכה על מגילה 7:5

Yehoshua b. Levi said: Women must drink four cups of wine on the night of the Seder (Pesaĥim 108b), read the megilla (Megilla 4a), and light Ĥanuka candles (Shabbat 23a) “for they too participated in that miracle.”

However, most commentaries understand that the words “they too” (“af hen”) indicate the primary obligation applies to men (who are obligated in time-bound positive mitzvot) and that women are obligated in the mitzva secondarily because “they too participated in that miracle” (Tosafot Pesaḥim 108b and Megilla 4a, Rashba, Ritva, Ran, Me’iri, and others).
