﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَرْفَعُوٓا۟ أَصْوَٰتَكُمْ فَوْقَ صَوْتِ ٱلنَّبِىِّ وَلَا تَجْهَرُوا۟ لَهُۥ بِٱلْقَوْلِ كَجَهْرِ بَعْضِكُمْ لِبَعْضٍ أَن تَحْبَطَ أَعْمَٰلُكُمْ وَأَنتُمْ لَا تَشْعُرُونَ ﴾

“O you who have attained to faith! Do not raise your voices above the voice of the Prophet, and neither speak loudly to him, as you would speak loudly to one another, lest all your [good] deeds come to nought without your perceiving it.”
