صحيح البخاري

Narrated Um-`Atiya:

We were ordered to go out (for `Id) and also to take along with us the menstruating women, mature girls and virgins staying in seclusion. (Ibn `Aun said, "Or mature virgins staying in seclusion)." The menstruating women could present themselves at the religious gathering and invocation of Muslims but should keep away from their Musalla.
