Why do Muslims abuse non-Muslims by calling them Kafirs?
Answer by Zakir Naik
Kafir means one who rejects.
Kafir is derived from the word kufr, which means to conceal or to reject. In Islamic terminology, Kafir means one who conceals or rejects the truth of Islam and a person who rejects Islam is in English called a non-Muslim.
If non-Muslims are hurt - they should accept Islam.
If any non-Muslim considers the word Kafir i.e. non-Muslim as an abuse, he may choose to accept Islam and then we will stop referring to him as or call him a kafir i.e. a non-Muslim.
