49:3
اِنَّ الَّذِيۡنَ يَغُضُّوۡنَ اَصۡوَاتَهُمۡ عِنۡدَ رَسُوۡلِ اللّٰهِ اُولٰٓئِكَ الَّذِيۡنَ امۡتَحَنَ اللّٰهُ قُلُوۡبَهُمۡ لِلتَّقۡوٰيؕ لَهُمۡ مَّغۡفِرَةٌ وَّاَجۡرٌ عَظِيۡمٌ
Indeed, those who lower their voices before the Messenger of Allah - they are the ones whose hearts Allah has tested for righteousness. For them is forgiveness and great reward
