Day Questions

Is it permissible for a woman to wear a wig instead of wearing the hair cover if other parts of the body that must be covered are covered, because it will not be her hair?

It is permissible if it fulfills the religious obligation of covering the hair, However, wearing a wig makes the woman appear as though she is without hijab, and this could discourage the wearing of hijab, so it becomes prohibited from this aspect.

If I masturbated when I was fasting for a nadhr (pledge), what should I do? I believe my fast was broken due to my ignorance and the sin of masturbation.
