Quran 5:72 – Difference Between Kufr And Kafir?
Because we are not God therefore we do not have divine information in this regard that which person has become kafir unless the person confesses to this fact himself. Therefore, an ideology can be called kufr or shirkiya but this does not mean that the person following that ideology is doing so intentionally or because of a genuine mistake in interpretation/understanding. Quran calls belief of trinity or people committing trinity as Kufr or kufriya practice in essence ( because it is in essence rejecting God ), and then later it is also informed that after itmam-e-hujjat, the truth has now becomes clear to people committing such acts and they were then called kafir too and the directive of punishment was given for those people of the book as well. But if a person who according to us is following a kufriya ideolody or a shirkiya ideology but claims to be a Muslim and presents his arguments to support his case, then we have no right to call that person Kafir, we can criticize the ideology but we cannot call that person Kafir instead he will be called a Muslim as per his claim.
