Umm 'Atiyya reported: The Messenger of Allaah (sallAllaahu alayhi wa sallam) commanded us to bring out on'id-ul-fitr and 'Id-ul-Adha young women, menstruating women and purdah-observing ladies, menstruating women kept back from prayer, but participated in goodness and supplication of the Muslims. I said: Messenger of Allaah, one of us does not have an outer garment. He said: Let her sister cover her with her outer garment. (Muslim, 1934)
