Fakir, faqeer, or faqīr (; Arabic: فقیر (noun of faqr)), derived from faqr (Arabic: فقر, 'poverty'), is an Islamic term traditionally used for Sufi Muslim ascetics who renounce their worldly possessions and dedicate their lives to the worship of God. They do not necessarily renounce all relationships, or take vows of poverty, but the adornments of the temporal worldly life are kept in perspective. The connotations of poverty associated with the term relate to their spiritual neediness, not necessarily their physical neediness.
