All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.
May Allaah reward you best for your concern to guide people and enjoin what is good and forbid what is evil. We implore Allaah to reward you and make you and us among those who are guided and who guide people.
Do not despair of people's response to virtue, for it was said before 'Umar Ibn Al-Khattaab embraced Islam that he would never do so. But Allaah guided him until he became the known righteous ‘Umar Al-Faarooq .
There are many ways of Da‘wah, such as giving out leaflets, booklets, tapes, face-to-face Da‘wah and others means. It is possible to distribute leaflets among males and females, but do not give them to men directly. You may do so through a female Mahram of theirs, your husband or a male Mahram of yours.
Allaah Knows best.
