Al-Laith b. Sa‘d quoted Ibn Abū Mulaika who quoted Yā'lā b. Mamlak as saying that he asked Umm Salama about the manner in which the Prophet recited, and she described it in a manner by which it was explained word by word.*
*This is explained as meaning that she showed how he pronounced each syllable distinctly, or simply that she gave an illustration of the fine quality of the Prophet’s recitation.
Ibn Juraij quoted Ibn Abū Mulaika who reported Umm Salama as saying, ‘God’s messenger used to make pauses in his recitation. He would say, ‘Praise be to God, the Lord of the universe’, then stop. He would next say, ‘The Compassionate, the Merciful’, then stop.”
Tirmidhī transmitted it, but he said that its isnād is not fully connected, because al-Laith transmitted this tradition from Ibn Abū Mulaika from Yā'lā b. Mamlak from Umm Salama, and al-Laith's tradition is sounder.
‘Uqba b. ‘Āmir reported God’s messenger as saying, “He who recites the Qur’ān loudly is like him who gives sadaqa openly, and he who recites the Qur’ān quietly is like him who gives sadaqa secretly.”
Tirmidhī, Abū Dāwūd and Nasā’i transmitted it, Tirmidhī saying this is a hasan gharīb tradition.
