Who Is Kafir With Whom Muslims Are Prohibited To Marry?
The Quran had the authority to declare the people who denied its message kafir or Mushrik. To label or declare someone kafir or Mushrik and to consider someone kafir or Mushrik are two different things. We can perceive kufr or shirk in someone or a group and then can decide accordingly, at the individual level, the way we do with other people with whom we do not feel comfortable with our religious beliefs.
