يا أَيُّهَا الَّذينَ آمَنوا لا تَرفَعوا أَصواتَكُم فَوقَ صَوتِ النَّبِيِّ وَلا تَجهَروا لَهُ بِالقَولِ كَجَهرِ بَعضِكُم لِبَعضٍ أَن تَحبَطَ أَعمالُكُم وَأَنتُم لا تَشعُرونَ

O you who have faith, don’t raise your voices above the Prophet’s, and don’t speak to him in a loud voice as you speak loudly to one another, lest your deeds become nullified without your awareness.
