Al Hujurat Ayah 3
إِنَّ ٱلَّذِينَ يَغُضُّونَ أَصْوَٲتَهُمْ عِندَ رَسُولِ ٱللَّهِ أُوْلَـٰٓئِكَ ٱلَّذِينَ ٱمْتَحَنَ ٱللَّهُ قُلُوبَهُمْ لِلتَّقْوَىٰۚ لَهُم مَّغْفِرَةٌ وَأَجْرٌ عَظِيمٌ ٣
Indeed, those who lower their voices in the presence of Allah’s Messenger are the ones whose hearts Allah has refined for righteousness. They will have forgiveness and a great reward.
