Dīn (دين, also anglicized as Deen) is an Arabic word commonly associated with Islam, but also used in Arab Christian worship. The term is sometimes translated as "religion", but as used in the Qur'an, it refers both to the path along which righteous Muslims travel in order to comply with divine law, or Shari'a, and to the divine judgment or recompense to which all humanity must inevitably face without intercessors before God. Thus, although secular Muslims^[who?] would say that their practical interpretation of Dīn conforms to "religion" in the restricted sense of something that can be carried out in separation from other areas of life, both mainstream and reformist Muslim writers take the word to mean an all-encompassing way of life carried out under the auspices of God's divine purpose as expressed in the Qur'an and hadith. As one notably progressive Muslim writer puts it, far from being a discrete aspect of life carried out in the mosque, "Islam is Dīn, a complete way of life"

How the term Dīn came to be used in Islamic Arabia is uncertain, but its use in modern Persian may derive etymologically from the Zoroastrian concept, Daena, which represents "insight" and "revelation", and from this "conscience" and "religion". Here, Daena is the Eternal Law, which was revealed to humanity through the Mathra-Spenta ("Holy Words"). Alternatively, the Hebrew term "דין", transliterated as "dīn", means either "law" or "judgement". In the Kabbalah of Judaism, the term can, alongside "Gevurah", refer to "power", and to "judgement".
