Overview
The face-veil portion is usually a rectangular piece of semi-transparent cloth whose top side is sewn to corresponding portion of the head-scarf, so that the veil hangs down loose from the scarf, and it can be turned up if the woman wishes to reveal her face (otherwise the whole face would be covered). In other cases, the niqāb part can be a side-attached cloth that covers the face below the eyes' region.
Many Muslims believe that the Islamic holy book, the Qur'an, and the collected traditions of the life of Muhammed, or hadith, require both men and women to dress and behave modestly in public. However, this requirement, called hijab, has been interpreted in many different ways by Islamic scholars (ulema) and Muslim communities (see Women and Islam). Some interpretations say that a veil is not compulsory in front of blind, asexual or gay men.
The Qur'an has been translated as stating:
"O Prophet! Say to your wives and your daughters and the women of the faithful to draw their outergarments (jilbabs) close around themselves; that is better that they will be recognized and not annoyed. And God is ever Forgiving, Gentle."
Qur'an Surah/Chapter Al-Ahzab Ayah/Verse 59Another verse in the Qur'an is translated as:
"And say to the faithful women to lower their gazes, and to guard their private parts, and not to display their beauty except what is apparent of it, and to extend their headcoverings (khimars) to cover their bosoms (jaybs), and not to display their beauty except to their husbands, or their fathers, or their husband's fathers, or their sons, or their husband's sons, or their brothers, or their brothers' sons, or their sisters' sons, or their womenfolk, or what their right hands rule (slaves), or the followers from the men who do not feel sexual desire, or the small children to whom the nakedness of women is not apparent, and not to strike their feet (on the ground) so as to make known what they hide of their adornments. And turn in repentance to Allah together, O you the faithful, in order that you are successful"
Qur'an Sura Nur Chapter: The Light. Verse 31A fatwa, written by Muhammed Salih Al-Munajjid on the Saudi Arabian website Islam QA, states:
The correct view as indicated by the evidence is that the woman's face is 'awrah which must be covered. It is the most tempting part of her body, because what people look at most is the face, so the face is the greatest 'awrah of a woman.
The fatwa also states when it is prohibited to wear the veil:
In the Sunnah there are many ahaadeeth, such as: the Prophet said: "The woman in ihraam is forbidden to veil her face (wear niqaab) or to wear the burqa'." This indicates that when women were not in ihraam, women used to cover their faces
