The Ruling on Secrecy in Knowledge and Religion

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Is speaking in secret forbidden? And what is the meaning of the statement of some of the Salaf: "If you find a group of people whispering to one another about their religion, know that they are upon misguidance or upon establishing misguidance"?

Answer:
Yes, because the religion should be made public, and knowledge should be made public. Therefore, secrecy in knowledge and religion is not permissible. Those who hold private gatherings for themselves are subject to suspicion. Knowledge is to be spread in the mosques and in the gatherings of people, and it is not to be kept in houses, or in rest houses, or in a place far from people, because that is a place of suspicion and doubt. Knowledge should be made public so that people benefit from it and the mosques, the houses of Allah the Exalted, are filled with it. Yes.
