The terms Kufr and Iman…

The terms Kufr and Iman (Disbelief and Belief) are in fact internal states, true; in outward matters we do use these terms for juridical rulings (marriage, burial, etc.) while the internal reality is for Allah to decide in the Hereafter. However, consider that saying “only Allah can judge me!” has connotations of both truth and misdirection at the same time – because no earthly judge is designating the person’s final abode to Heaven or Hellfire, but at the same time Allah through the revealed Shariah has allowed judges on this Earth to give verdicts connected to matters like permissibility of a person’s marriage or one’s burial place as they are connected with one’s Deen.
