Surah Al-Hujraat Verse 2 - English Translation by Shabbir Ahmed
Surah Al-Hujraatيَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَرۡفَعُوٓاْ أَصۡوَٰتَكُمۡ فَوۡقَ صَوۡتِ ٱلنَّبِيِّ وَلَا تَجۡهَرُواْ لَهُۥ بِٱلۡقَوۡلِ كَجَهۡرِ بَعۡضِكُمۡ لِبَعۡضٍ أَن تَحۡبَطَ أَعۡمَٰلُكُمۡ وَأَنتُمۡ لَا تَشۡعُرُونَ
O You who have chosen to be graced with belief! Raise not your voices above the voice of the Prophet, nor shall you speak loudly to him, as you would speak loudly to one another, lest your works be rendered vain while you perceive not. (In my opinion, this verse applies today as well. We must be respectful whenever we speak of or even think of him)
