The discussion of Islam and their view of the Koran is constantly ”under fire” where everyone has an opinion, even the non-muslims. In this paper, the goal was to find out how the believers themselves interpret and see the Koran. The focus of this study is mainly on two suras in Koran, sura 4 verse 3 and sura 4 verse 129. The purpose of the study is to analyze the Muslim feminist authors’ views on polygamy and their focus on the two suras. The material is from four different feminist authors that writes about polygamy, their view and opinion on polygamous marriages and about the polygamous message in the Koran. The study demonstrates that the feminist authors argue from similar basis when discussing polygamy. The two most common arguments that the authors use is argument of fairness, where there is no logic to why, the otherwise so fair God, isn’t it then it comes to the terms of polygamy. Another argument that the authors bring up is the evolutionary argument, which the authors believe that the interpreters of the Koran in the present should take into account the historical development when they interpret the suras. The four different authors bring up similar arguments but different views on how polygamy in Islam and in the Koran should and can be interpreted.
