Quran Ayats (Verses) regarding Dont raise your voice above Prophets voice

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَرۡفَعُوٓاْ أَصۡوَٰتَكُمۡ فَوۡقَ صَوۡتِ ٱلنَّبِيِّ وَلَا تَجۡهَرُواْ لَهُۥ بِٱلۡقَوۡلِ كَجَهۡرِ بَعۡضِكُمۡ لِبَعۡضٍ أَن تَحۡبَطَ أَعۡمَٰلُكُمۡ وَأَنتُمۡ لَا تَشۡعُرُونَ

2.0 believers! Do not raise your voices above the voice(3) of the Prophet (Prophet Muhammad), and do not(4) speak aloud in his presence as you speak aloud to one another, lest your deeds become in vain, while you are unaware.

Surah Name : Al-Hujurat   Surah Number : 49   Ayat Number: 2

إِنَّ ٱلَّذِينَ يَغُضُّونَ أَصۡوَٰتَهُمۡ عِندَ رَسُولِ ٱللَّهِ أُوْلَـٰٓئِكَ ٱلَّذِينَ ٱمۡتَحَنَ ٱللَّهُ قُلُوبَهُمۡ لِلتَّقۡوَىٰۚ لَهُم مَّغۡفِرَةٞ وَأَجۡرٌ عَظِيمٌ

3. Undoubtedly, those who lower (5) their voices in the presence of the Messenger of Allah, are the ones whose hearts Allah has tested for piety. For them is forgiveness and a great reward.
