الجواب حامدا و مصلیا
It is not only permissible, but also incumbent, for a woman to seek the necessary knowledge about her religion. If after being taught necessary knowledge, it is better if extra education can be provided for her within the boundaries of her home, otherwise it is also permissible for her to learn in a protected environment (i.e. madrasa etc.). It is also permissible for men to teach women with proper observance the boundaries of modesty and Hijab, on the condition that there be no fear of temptation.
