Under Muslim Sharia Law, the Muslim women can only marry Muslim men whereas a Sunni male can marry a Muslim female (Of any sect) or a Kitabia i.e. a woman who believes in a revealed religion possessing a Divine Book viz Islam, Christianity and Judaism and is valid under the Sunni Law but he cannot marry an idolatress or a fire-worshiper. A marriage, however with a idolatress or a fire worshiper is merely irregular in Sunni Law, but void in Shia Law. A Muslim woman cannot marry any man who is not a Muslim, whether he is Kitabia or not .
