Sudan, Congo, Chad and Afghanistan came up as the 4 worst for women's rights and of the ten worst was Guatamala, Pakistan, India, Iraq, Mali. Chad was the worst. And those countries are mixture of religions.
It depends on what factors you want to look at and emphasize when making your list. I worked with the Economist Intelligence Unit's Women Economic Opportunity Index and one thing that was decided to do was the emphasize every variable with equal weight and then make the data open source so that others could adjust the weights as they like. The countries will shift depending on what you consider to be more important.
If you want the country with the highest birth rate for the lowest economic quintile of population for example you get Niger.
If you want the rape capitals of the world you'll get the Congo, South Africa, and perhaps India.
If you want lack of security Afghanistan, the Congo, Sudan, Pakistan then become major players.
If you want lack of land ownership rights and little access to financial credit then much of Sub-Saharan Africa from Niger to Malawi becomes highlighted.
Middle Eastern countries tend to do a lot better in the areas of women's education and health opportunities (in part, because they aren't as poor), and, depending on the country, market and job access.
