10. Jews and Muslims both traditionally segregate men and women during worship services
Within Judaism, this practice of separately seating male and female worshippers varies by branch or denomination. In Orthodox synagogues, Jewish men and women sit in separate areas of their own (there is often an upstairs gallery for women), whereas in Reform synagogues the sexes are not separated from each other.
In Islam, segregation of the sexes during prayer also prevails, but specific customs vary from culture to culture and place to place. Often only Muslim men pray at mosques, while women are expected to pray at home; elsewhere, Muslim women may pray at a mosque, but generally do so either in the rear of the prayer hall (behind the men) or else in an altogether separate area of their own, sometimes hidden from view by a partition, or in an upstairs gallery or a different room.
