I am asking this question because of this question from Islam.SE.
It seems that "unbeliever" can be used for a person "who does not
believe" whereas "disbeliever" can be used for a person "who is
presented and rejected". The prefix "dis" can be used for rejection
(compared to the prefix "un" which can be used for "not" without
rejection). So "disbelieve" seems to imply "making a conscious
decision" to reject/dismiss something.
How correct is above explanation. Can someone explain in more detail what is, if any, the difference between those two words?

That seems a reasonable definition. Unbeliever or non-believer is someone who is outside the faith, either by choice or because they haven't been told. Disbeliever implies a deliberate and definite rejection of the belief.
