Sharing a Faa’idah from Shaikh Uthaymeen -[One of The Reasons a Shaikh May Not Want His Speech to Be Recorded]
In The Name of Allaah, The Most Merciful, The Bestower of Mercy
If a person were to say: “From the fruits [or benefits] of knowledge is that it is disseminated to the people; therefore, if one of the Mashaayikh were to say, ‘Do not record my speech in audio tapes’, then what is to be said [or the verdict] regarding this affair?’ ‘’
Answer: If he [i.e. the Shaikh] said, “Do not record my speech”; it is his right [i.e. to say this and he is not to be recorded], because it maybe that he makes a mistake in a statement and it gets recorded in that cassette, and thus the people become misguided by that statement.
