"Nearly every Arab country has similar laws, rooted in Islamic precepts that emphasize paternity as the source of identity. Women's groups have succeeded in changing such laws in Egypt, Morocco and Algeria and are leading campaigns elsewhere, usually against religious conservatives. In Lebanon, reformers are finally gaining attention for the issue - through a series of small public protests like one that Solh recently attended, of 100 people, on Beirut Martyrs' Square."
PS Of course, those nationality laws are not Islamic but copied (word for word in many cases) from British and Western nationality laws.
