Praise be to Allaah.
A woman can do da’wah inside her home, with her
husband and mahrams, men and women alike. She can also do da’wah outside
the home, to other women, so long as this does not involve travelling
without her husband or mahram, and there is no fear of fitnah
(temptation), and this is done with the husband’s permission if she is
married and there is a need for that, and this does not lead to her
neglecting her primary duties, which are towards her own family.
