The questioner says, "May Allah be good to you (O) possessor of nobility. Presently every time a scholar refutes another's mistake it is said, 'This is the speech of peers about one another so close this affair, it is not to be looked at, (nor given any credence)'. What is your opinion concerning this principle and is it applicable unrestrictedly?"
Ash-Shaikh Al 'Allaamah, Saalih Al Fawzaan who is a member of the Council of Major Scholars and the Permanent Committee for Islamic Rulings responded by saying,
I have clarified this to you all (before). It is a must that the truth is clarified, it is incumbent to explain to the truth and to refute falsehood. We don't appease anyone, we don't indulge (those mistaken). We clarify the error to point out the truth and that which opposes this error. We don't have a concern for this one or that one (which prevents us from refuting their error).
It is not permissible to be silent (about errors). Verily, if we were to be quite about this error, then (quiet about) a second, then (quiet about) a third; the errors would become many and the people would believe that the silence of the scholars constitutes a proof (for the legitimacy of these errors).
Therefore, clarifying (these errors) are a must. Especially if the one who made the error is an example, the people have taken him as an example; or he is in an authoritative position and has erred. So the error is clarified in order that (no one) is deceived due to him. Yes.
It should not be said, "Close (this affair), do not look at it nor give it credence," hate it who hates it and like it who likes it. This is because our goal and aim is the truth. Our goal and aim is not (persuaded) by the concern for personalities nor (is it our aim) to defame them.
