A niqab or niqāb (/nɪˈkɑːb/; Arabic: نِقاب niqāb, "[face] veil"; also called a ruband) is a garment of clothing that covers the face, worn by some Muslim women as a part of a particular interpretation of hijab (modest dress). According to the majority of Muslim scholars and Islamic schools of thought, face veiling is not a requirement of Islam; however a minority of Muslim scholars, particularly among the Salafi movement, assert that women are required to cover their face in public. Those Muslim women who wear the niqab, do so in places where they may encounter non-mahram (non-related) men.
The face veil pre-dates Islam, and had been used by certain Arabian pre-Islamic cultures. Culturally, it is "a custom imported from Najd, a region in Saudi Arabia and the power base of its Salafi fundamentalist form of Islam. Within Muslim countries it is very contested and considered fringe." [1] [2]
Today, the niqab is most often worn in its region of origin: the Arab countries of the Arabian Peninsula — Saudi Arabia, Yemen, Oman, and the United Arab Emirates. However, even in these countries, the niqab is neither a universal cultural custom nor is it culturally compulsory. In other parts of the Muslim world outside of the Arabian Peninsula, where the niqab has slowly spread to a much smaller extent, it is regarded warily by Sunni and non-Sunni Muslims alike "as a symbol of encroaching fundamentalism." [3] Nevertheless, the niqab is worn by a small minority of Muslims in not only Muslim-majority regions such as Somalia, Syria, Afghanistan, Pakistan, Bangladesh, the Palestinian territories, and Southern Iran, but also among a minority of Muslims in regions where Muslims are themselves a minority, like India and Europe.
The terms niqab and burqa are often conflated; a niqab covers the face while leaving the eyes uncovered, while a burqa covers the entire body from the top of the head to the ground, with only a mesh screen allowing the wearer to see in front of her.
Niqab (n.) A face veil covering the lower part of the face (up to the eyes) worn by observant Muslim women.
Nirvana (n.) In the Buddhist system of religion, the final emancipation of the soul from transmigration, and consequently a beatific enfrachisement from the evils of wordly existence, as by annihilation or absorption into the divine. See Buddhism.
Compare: Buddhism
Buddhism (n.) The religion based upon the doctrine originally taught by the Hindu sage Gautama Siddartha, surnamed Buddha, "the awakened or enlightened," in the sixth century b. c., and adopted as a religion by the greater part of the inhabitants of Central and Eastern Asia and the Indian Islands. Buddha's teaching is believed to have been atheistic; yet it was characterized by elevated humanity and morality. It presents release from existence (a beatific enfranchisement, Nirv[^a]na) as the greatest good. Buddhists believe in transmigration of souls through all phases and forms of life. Their number was estimated in 1881 at 470,000,000.
Buddhism (n.) A religion represented by the many groups (especially in Asia) that profess various forms of the Buddhist doctrine and that venerate Buddha.
Buddhism (n.) The teaching of Buddha that life is permeated with suffering caused by desire, that suffering ceases when desire ceases, and that enlightenment obtained through right conduct and wisdom and meditation releases one from desire and suffering and rebirth.

Nirvana (n.) Any place of complete bliss and delight and peace [syn: Eden, paradise, nirvana, heaven, promised land, Shangri-la].
