Messenger of Allah ﷺ said, "Allah does not listen to a prophet as He listens to a prophet who recites the Qur'an in a pleasant tone." The companion of the sub-narrator (Abu Salama) said, "It means, reciting it aloud."  

قَالَ رَسُولُ اللَّهِ ﷺ لَمْ يَأْذَنِ اللَّهُ لِشَىْءٍ مَا أَذِنَ لِلنَّبِيِّ ﷺ يَتَغَنَّى بِالْقُرْآنِ وَقَالَ صَاحِبٌ لَهُ يُرِيدُ يَجْهَرُ بِهِ  

That the Prophet ﷺ said to him' "O Abu Musa! You have been given one of the mazamir (sweet melodious voices) of the family of David.'  

عَنِ النَّبِيِّ ﷺ قَالَ لَهُ يَا أَبَا مُوسَى لَقَدْ أُوتِيتَ مِزْمَارًا مِنْ مَزَامِيرِ آلِ دَاوُدَ
