Kafir

Kafir is an Arabic word meaning “nonbeliever” or “infidel” (plural: kuffar). The term kafir derives from the Islamic word kufr (disbelief), used to describe those who deny Allah’s authority or teachings.

Kufr may take the form of denying and rejecting.

Kufr is the denial and concealment of the Truth such as those who deny the obligation of Salah, Zakah, Sawm, Hajj in case of being financially and physically able, and dutifulness to one’s parents, and so on. It is also like those who deny the prohibition of Zina (premarital sexual intercourse and/or adultery), consuming Khamr (intoxicants), and disobeying one’s parents.
