Sayyidah Umm Atiyyah al-Ansariyyah (may Allah be pleased with her) said: The Messenger of Allah (peace and blessings be upon him) commanded us to bring out, on the day of Eid, the young unmarried girls, the women kept in seclusion, and the menstruating women; as for the menstruating women, they would attend the prayer-ground of the Muslims.
