Is silence regarding the vocalization of the reciter's words considered approval?

The questioner:
He says: Honorable Shaykh, may Allah grant you success, does your silence regarding the vocalization of the brother reciter's reading constitute approval of it and correction of his recitation?

The Shaykh:
In what respect?

The questioner:
Vocalizing the words is considered approval of it and correction of his recitation; because we love to combine the two good things: jurisprudence and language. He read just now "la thaman malk," like this. Is this the pronunciation, or is it with a dammah?

The Shaykh:
I do not know what the phrase you read was. This is up to you, it is not up to me. Yes.

The questioner:
And he says: "la min ra's mal wa thaman malk."

The Shaykh:
And what did you read it as?

The questioner:
With a kasrah on the mīm: "malk."

The Shaykh:
It is not permissible. "Malk" is permissible. "Malk" and "malk" do not contradict each other. Correct your understanding, you who are asking. Yes.
