Verse 2

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَرْفَعُوٓا۟ أَصْوَٰتَكُمْ فَوْقَ صَوْتِ ٱلنَّبِىِّ وَلَا تَجْهَرُوا۟ لَهُۥ بِٱلْقَوْلِ كَجَهْرِ بَعْضِكُمْ لِبَعْضٍ أَن تَحْبَطَ أَعْمَـٰلُكُمْ وَأَنتُمْ لَا تَشْعُرُونَ

O you faithful; do not raise your voices above the voice of the prophet, nor shall you speak loudly to him, as you speak loudly to one another, lest you nullify your works while you do not perceive.
