Is it permissible to call a man an open sinner if he is committing a sin, such as shaving the beard?

The questioner : Is it permissible to say to a man, "So-and-so is an open sinner," if he is committing a sin, such as shaving the beard? Who is speaking? For example, shaving the beard and other sins, since some young people mock them, interpreting the term.

The Shaykh : Yes, if we see a man persisting in a sin, even if it is a minor one, he is an open sinner.

The questioner : But is it appropriate to say, "I will call him an open sinner"?

The Shaykh : It is not appropriate, because Allah says, "Do not insult one another with bad names." However, we rule that he is an open sinner, so anything that requires justice, he is deprived of it. Did you understand? As for the matter of saying "open sinner" or calling out to him, saying "O open sinner," no, that does not benefit.
