'Abdullah ibn Burayda related that his father said, "The Prophet, may Allah bless him and grant him peace, went out to the mosque while Abu Musa was reciting and asked, 'Who is this?' 'I am Burayda,' I replied, 'May I be your ransom!' He said, 'This man has been given one of the flutes of the family of Da'ud.'"

حَدَّثَنَا عَلِيُّ بْنُ الْحَسَنِ، قَالَ: أَخْبَرَنَا الْحُسَيْنُ، قَالَ: حَدَّثَنَا عَبْدُ اللهِ بْنُ بُرَيْدَةَ، عَنْ أَبِيهِ: خَرَجَ النَّبِيُّ صلى الله عليه وسلم إِلَى الْمَسْجِدِ وَأَبُو مُوسَى يَقْرَأُ، فَقَالَ: مَنْ هَذَا؟ فَقُلْتُ: أَنَا بُرَيْدَةُ جُعِلْتُ فِدَاكَ، قَالَ: قَدْ أُعْطِيَ هَذَا مِزْمَارًا مِنْ مَزَامِيرِ آلِ دَاوُدَ.
