Kafir

"Kafir" is an Arabic term used in Islam to describe someone who does not believe in or openly rejects the core tenets of the faith, particularly the belief in the oneness of God (Allah) and the teachings of Prophet Muhammad. It is often translated as "disbeliever" or "non-believer." The term's usage varies contextually, and it can carry different connotations depending on cultural, theological, or interpersonal circumstances. However, it is fundamentally a descriptor for those outside the Islamic faith, emphasizing the importance of faith acceptance within Islamic theology.
