Is it permissible for a woman to perform Da`wah (calling to Islam) outside her home, and if so, how should she do it?
A woman can perform Da`wah inside her home, with her husband and Mahrams (spouse or permanently unmarriageable relative); men and women alike. She can also performed Da`wah outside her home to other women, (Part No. 12; Page No. 250) as long as this does not involve traveling without her husband or mahram, and there is no fear of fitnah (temptation). Also, this should be done with the husband's permission if she is married. She can do so if there is a need for that, and if doing so does not lead to neglecting her primary duties, which are towards her own family.May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions.
