Use your professional skills for the community. If you can write well, establish a well-written, organized and attractive community newsletter. If you're in business, establish a community fundraising project for the local mosque's expansion. Use what you've got. It'll take some thinking and planning, but you're almost bound to find a way you can contribute, if Allah wills.
Muslim women have their own heroes.
Remember that Muslim women's history does not start and end with these four righteous women. Muslim history is full of women who have made positive contributions. We also need to recognize and know the efforts of the pioneering Muslim women who came to North America and worked in partnership with men to establish the various Muslim institutions now flourishing in North America. Know the history of the first generation of Muslim women as well as those who established the Muslim community in North America. Read to your daughters the stories of the great female companions of the Prophet in books like Abdul Wahid Hamid's Companions of the Prophet .
