Many people / writers have discussed the status of women in pre-Islamic Arabia, and their findings have been mixed. Under the customary tribal law existing in Arabia at the advent of Islam, women as a general rule had virtually no legal status. They were sold into marriage by their guardians for a price paid to the guardian, the husband could terminate the union at will, and women had little or no property or succession rights. Other writers, on the contrary, have agreed that women's status in pre-Islamic Arabia was poor, citing practices of female infanticide, unlimited polygyny, patrilineal marriage, and others. Saudi historian Hatoon al-Fassi considers much earlier historical origins of Arab women's rights. Using evidence from the ancient Arabian kingdom of Nabataea, she finds that Arab women in Nabataea had independent legal personalities. She suggests that they lost many of their rights through ancient Greek and Roman law prior to the arrival of Islam and that these Greco-Roman constraints were retained under Islam. Valentine M. Moghadam analyzes the situation of women from a marxist theoretical framework and argues that the position of women is mostly influenced by the extent of urbanization, industrialization, proletarianization and political ploys of the state managers rather than culture or intrinsic properties of Islam; Islam, Moghadam argues, is neither more nor less patriarchal than other world religions especially Christianity and Judaism.
