Allah has not heard anything (more pleasing) than listening to the Prophet reciting the Qur'an in a sweet loud voice. (Using translation from Muslim 793b)  

قَالَ رَسُولُ اللَّهِ ﷺ «مَا أَذِنَ اللَّهُ لِشَيْءٍ كَإِذْنِهِ لِنَبِيٍّ يَتَغَنَّى بِالْقُرْآنِ يَجْهَرُ بِهِ»  

"The Messenger of Allah ﷺ heard the recitation of Abu Musa and said: 'This man has been given a Mizmar among the Mazamir of the family of Dawud, peace be upon him.'" (Using translation from Nasāʾī 1020)   

سَمِعَ النَّبِيُّ ﷺ أَبَا مُوسَى وَهُوَ يَقْرَأُ فَقَالَ «لَقَدْ أُوتِيَ هَذَا مِنْ مَزَامِيرِ آلِ دَاوُدَ»  

[Machine] The Prophet ﷺ said, "He is not one of us who does not find delight in the Quran."  

أَنَّ النَّبِيَّ ﷺ قَالَ «لَيْسَ مِنَّا مَنْ لَمْ يَتَغَنَّ بِالْقُرْآنِ»  

[Machine] "From the Prophet, peace be upon him, he said: 'Allah has not granted permission for something that He has granted permission to a prophet to indulge in reciting the Qur'an.' Abu Muhammad said: 'He intends to be self-sufficient through it.'"  

عَنِ النَّبِيِّ ﷺ قَالَ «مَا أَذِنَ اللَّهُ لِشَيْءٍ مَا أَذِنَ لِنَبِيٍّ يَتَغَنَّى بِالْقُرْآنِ» قَالَ أَبُو مُحَمَّد «يُرِيدُ بِهِ الِاسْتِغْنَاءَ»
