Fakir, faqeer, or faqīr, derived from faqr, 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.

Asceticism is a lifestyle characterized by abstinence from sensual pleasures, often for the purpose of pursuing spiritual goals. Ascetics may withdraw from the world for their practices or continue to be part of their society, but typically adopt a frugal lifestyle, characterised by the renunciation of material possessions and physical pleasures, and also spend time fasting while concentrating on the practice of religion or reflection upon spiritual matters, which is thought by some to allow the practitioner's core of consciousness to expand and connect with the infinite universal consciousness. Some individuals have also attempted an ascetic lifestyle to free themselves from addictions to things such as alcohol, tobacco, drugs, entertainment, sex, food, etc.
