‘Abd ar-Rahman b Sa'd b. 'Ammar b. Sa‘d, the mu’adhdhin* of God’s Messenger, said that his father told him from his father from his grandfather that God’s Messenger commanded Bilal to put his fingers in his ears, saying that it made the voice louder.
* The mu’adhdhin here mentioned was Sa‘d, great-grandfather of ‘Abd ar-Rahman.
Malik heard that the mu'adhdhin came to ‘Umar to call him to the Morning Prayer. Finding him asleep, he said, “Prayer is better than sleep," and ‘Umar commanded him to include it in the call to Morning Prayer.
