Dīn (Arab.). Life-way or religion, most particularly Islam. The whole system is sometimes referred to as dīn wa-dawla, ‘religion and state (combined)’, there being no distinction within Islam between ‘religion and politics’. The word as used in the Qurʾān is probably derived from a Christian source which had already borrowed from the Iranian dēn, religion. Other Arabic meanings are: judgement or retribution (as in yaum al-dīn, day of judgement); custom or usage.
