Burayda said, "The Messenger of Allah, may Allah bless him and grant him peace, went out to the mosque while Musa was reciting. He said, 'Who is it?' I said 'I am Burayda, may I be your ransom!' The Prophet (ﷺ) said, 'This man has been given one of the flutes of the family of Da'ud.'"

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