The ruling on wiping over the head covering known as the shaylah, and over hair dyed with henna

Question:
May Allah reward you. In her second question, she says: When I put henna on my head and then I want to perform wudu, I wipe over the shaylah on top of the henna. Is my wudu valid, or must I remove the shaylah, the woman's head covering, and then wipe over my hair, which has the henna on it? May Allah reward you with good.

Answer:
It is not permissible to wipe over the shaylah; rather, one wipes over the head, even if there is henna on it, because the henna does not prevent the water from reaching the hair. So she wipes over her head and does not wipe over the shaylah, because this is not sufficient and is not considered wiping over the head. Yes.
