يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَرْفَعُوا أَصْوَاتَكُمْ فَوْقَ صَوْتِ النَّبِيِّ وَلَا تَجْهَرُوا لَهُ بِالْقَوْلِ كَجَهْرِ بَعْضِكُمْ لِبَعْضٍ أَن تَحْبَطَ أَعْمَالُكُمْ وَأَنتُمْ لَا تَشْعُرُونَ
[49:2]
O you who believe! do not raise your voices above the voice of the Prophet, and do not speak loud to him as you speak loud to one another, lest your deeds became null while you do not perceive.
O ye who believe! Raise not your voices above the voice of the Prophet, nor speak aloud to him in talk, as ye may speak aloud to one another, lest your deeds become vain and ye perceive not.
O ye who believe! Lift not up your voices above the voice of the Prophet, nor shout when speaking to him as ye shout one to another, lest your works be rendered vain while ye perceive not.
