Umm Yasmin, of the Centre for Muslim Minorities and Islam, says that feminism is often mistaken as a western movement, but that Muslim feminists have been active since the early nineteenth century. Muslim feminists tasks aren't to reform the religion of Islam, but rather "promote gender equality within a secular society". Yasmin further concludes that Muslim feminists have "adapted" their views "in which Islam can be contextualized" in order to advocate equality between men and women paralleling with their faith; for Islam doesn't condone violence against women. Since the nineteenth century, both men and women question the legal system regarding the Sharia Laws effect on women such as strict veiling, education, seclusion, polygyny and concubinage. In reforming these social issues, Muslim women started advocating for legal change, establishing schools for girls, and opposing to veiling and polygyny. In support of Yasmin's argument, Fatema Mernissi undermines that the ideal Muslim woman being portrayed as "silent and obedient" has nothing to do with the message of Islam. In her view, conservative Muslim men manipulated the religious texts of the Quran to preserve their patriarchal system in order to prevent women from sexual liberation; thus enforcing justification of strict veiling and limitation rights.
