To evaluate the effect of Islam on the status of women, many writers have discussed the status of women in pre-Islamic Arabia, and their findings have been mixed. Some writers have argued that women before Islam were more liberated, drawing most often on the first marriage of Muhammad and that of Muhammad's parents, but also on other points such as worship of female idols at Mecca. Other writers, on the contrary, have argued that women's status in pre-Islamic Arabia was poor, citing practices of female infanticide, unlimited polygyny, patrilineal marriage and others.
