Is there evidence for placing the fingers in the ears during the adhan for prayer?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: There is a phenomenon among many mu'adhdhins, which is that they do not place their fingers in their ears during the adhan, and they say that this is not established. What is your view, may Allah preserve you?

Answer:
How do they know that it is not established? This is a report that exists in the Sunnah. Ah. They say that it helps in raising the voice; it helps the mu'adhdhin to raise his voice, and it is a sunnah (recommended practice). Whoever places his fingers in his ears, it is a sunnah (recommended practice), and whoever does not place them, Bilal (may Allah be pleased with him), the mu'adhdhin of the Messenger of Allah (peace and blessings be upon him), used to do this in the presence of the Prophet (peace and blessings be upon him). Yes.
