Araf, Al [the partition].
A region, according to the Koran, between Paradise and Jehennam, for those who are neither morally good nor bad, such as infants, lunatics, and idiots. The inmates of Al Araf will be allowed to converse with the blessed and the cursed; to the former this region will appear a hell, to the latter a heaven. (See LIMBO.)
