Allah Ta’ala says, ?They (females) should not make apparent their adornment.? (Nur 30).
The word, ?adornment? refers to ?places of adornment, e.g. hair, ears, neck, etc.? (Ma?riful Qur’aan vol.6 pg.384; Darul Kutub). Allaamah ibn Katheer (RA) has expressly included ?Dhawaaib? (locks of hair) under the word adornment. (Ibn Katheer vol.3 pg.294; Darul Ma?rif). In view of the above, it is imperative that the hair must not be seen at all. Wearing a thin scarf wherein the hair, being an area of adornment, is exposed is contrary to the above mentioned order of Allah Ta’ala.
and Allah Ta’ala Knows Best
