Mishkat al-Masabih #2108

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.
