وَعَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «خُفِّفَ عَلَى دَاوُدَ الْقُرْآنُ فَكَانَ يَأْمُرُ بِدَوَابِّهِ فَتُسَرَّحَ فَيَقْرَأُ الْقُرْآنَ قَبْلَ أَنْ تُسَرَّحَ دَوَابُّهُ وَلَا يَأْكُلُ إِلَّا مِنْ عملِ يدَيهِ» . رَوَاهُ البُخَارِيّ

Abu Huraira reported the Prophet as saying, “Recitation of Scripture was made easy for David, who would order his beasts to be saddled and recite the Scripture before they had been saddled; and he would eat only what his hands had earned.” Bukhari transmitted it.
