Prayer at Night - Section 2
وَعَن أبي هُرَيْرَة قَالَ: كَانَ قِرَاءَةُ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِاللَّيْلِ يَرْفَعُ طَوْرًا وَيَخْفِضُ طَوْرًا. رَوَاهُ أَبُو دَاوُدَ
Abu Huraira said that the Prophet’s recitation at night was partly in a loud voice and partly in a low voice. Abu Dawud transmitted it.
