The interpretation of the ḥijāb as separation can be digested in three ways: as a visual barrier, physical barrier, and ethical barrier.
The visual barrier has the opportunity to hide something from sight which places emphasis on a symbolic boundary (for example, between the Prophet's family and the surrounding community).
(dialectal)) is a veil worn by some Muslim women in the presence of adult males outside of their immediate family, which usually covers the head and chest.
The word ḥijāb in the Quran refers not to women's clothing, but rather a spatial partition or curtain.
Some scholars oppose face covering, particularly in the West, where the woman may draw more attention as a result.
