“A woman needs to be confined within a framework that is controlled by the man of the house,” Osama Yehia Abu Salama, a Brotherhood family expert, said of the group’s general approach, speaking in a recent seminar for women training to become marriage counselors. Even if a wife were beaten by her husband, he advised, “Show her how she had a role in what happened to her.”

“If he is to blame,” Mr. Abu Salama added, “she shares 30 percent or 40 percent of the fault.”

Now, with a leader of the Brotherhood’s political arm in Egypt’s presidential palace and its members dominating Parliament, some deeply patriarchal views the organization has long taught its members are spilling into public view. The Brotherhood’s strident statements are reinforcing fears among many Egyptian liberals about the potential consequences of the group’s rise to power and creating new awkwardness for President Mohamed Morsi as he presents himself as a new kind of moderate, Western-friendly Islamist.

In a statement Wednesday on a proposed United Nations declaration to condemn violence against women, the Brotherhood issued a list of objections, which formally laid out its views on women for the first time since it came to power.

In its statement, the Brotherhood said that wives should not have the right to file legal complaints against their husbands for rape, and husbands should not be subject to the punishments meted out for the rape of a stranger.

A husband must have “guardianship” over his wife, not an equal “partnership” with her, the group declared. Daughters should not have the same inheritance rights as sons. Nor should the law cancel “the need for a husband’s consent in matters like travel, work or use of contraception” — a reform in traditional Islamic family law that was enacted under former President Hosni Mubarak and credited to his wife, Suzanne.
