Surat Al-Ĥujurāt - سورة الحجرات

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَرْفَعُوا أَصْوَاتَكُمْ فَوْقَ صَوْتِ النَّبِيِّ وَلَا تَجْهَرُوا لَهُ بِالْقَوْلِ كَجَهْرِ بَعْضِكُمْ لِبَعْضٍ أَن تَحْبَطَ أَعْمَالُكُمْ وَأَنتُمْ لَا تَشْعُرُونَ

Muhsin Khan: O you who believe! Raise not your voices above the voice of the Prophet (SAW), nor speak aloud to him in talk as you speak aloud to one another, lest your deeds may be rendered fruitless while you perceive not.
