Read women that fear Allah subhnna wa tallah

Teach the wives and daughters the value of wearing niqab; teach and encourage them in this matter.

Teach the male muslim the importance of respecting a muslimah's privacy, that he should not even inquire about the physical appearance of a woman for personal reasons.

Fear Allah's commands only... not the criticisms of the kafr.

Recognize that wearing niqab is a blessing and protection for the woman, not a stifling command.

Do not judge those who do not wear niqab; instead, show them Qur'an and Sunnah on the matter and the rest is, as they say, "on them" to decide.  Allah, subhana watala, is the only true Judge.

Do not be alone with persons of the opposite sex.
