Praise be to Allaah.
Whoever says that women should not pray Eid in the mosque should note that the Prophet (peace and blessings of Allaah be upon him) commanded women to go out to the Eid prayers. It was narrated that Umm ‘Atiyyah said: “We were commanded to go out on the day of Eid, even to bring out the virgins from their seclusion and the menstruating women, who would be behind the people, joining in their takbeer and du’aa’s, sharing the blessings of this day.” (Narrated by al-Bukhaari, al-Jumu’ah, 918)
But if a woman is menstruating she should keep away from the prayer place and not enter it, but she should witness the good and the du’aa’ of the Muslims, and listen to the khutbah from outside the prayer place. A woman should avoid wearing adornments and go out wearing old clothes which do not form any kind of adornment in themselves, so that she will not be a source of temptation to men. She should not go out wearing perfume. ‘Abd-Allaah ibn al-Mubaarak said, “If a woman insists on going out, then her husband should give her permission to go out wearing old clothes and not wearing adornments. If she insists on that then the husband has the right to prevent her from going out.” And Allaah knows best.
