Some Muslim girls only wear a head scarf with the face open while others wear a Niqab where only the eyes are visible. Which is the correct way? As eyes can also be a source of attraction and they are allowed to be revealed why not the head as well?
Most of our Maraaji' of Taqleed state that covering the face of the female is not obligatory except when not covering the face can cause harm, but in usual cases, it is obligatory to cover all the hair, head, neck and whole body except the face and the hands.
Wassalam.
