Hadith 1210
Ya'la b. Mamlak said he asked Umm Salama, the Prophet’s wife, about his recitation and prayer. She Said, “What have you to do with his prayer? He would pray, then sleep as long as he had prayed, then pray as long as he had slept, then sleep as long as he had prayed, till morning.” She then described his recitation and did so with an exposition word by word. Abu Dawud, Tirmidhi and Nasa’i transmitted it.
وَعَن يَعْلَى بْنِ مُمَلَّكٍ أَنَّهُ سَأَلَ أُمَّ سَلَمَةَ زَوْجَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ قِرَاءَةِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَصَلَاتِهِ؟ فَقَالَتْ: وَمَا لَكُمْ وَصَلَاتُهُ؟ كَانَ يُصَلِّي ثُمَّ يَنَامُ قَدْرَ مَا صَلَّى ثُمَّ يُصَلِّي قَدْرَ مَا نَامَ ثُمَّ يَنَامُ قَدْرَ مَا صَلَّى حَتَّى يُصْبِحَ ثُمَّ نَعَتَتْ قِرَاءَتَهُ فَإِذَا هِيَ تَنْعَتُ قِرَاءَةً مُفَسَّرَةً حَرْفًا حَرْفًا) رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَالنَّسَائِيُّ
