49:3

Al-Hujuraat 49:3

إِنَّ ٱلَّذِينَ يَغُضُّونَ أَصْوَٰتَهُمْ عِندَ رَسُولِ ٱللَّهِ أُو۟لَٰٓئِكَ ٱلَّذِينَ ٱمْتَحَنَ ٱللَّهُ قُلُوبَهُمْ لِلتَّقْوَىٰ ۚ لَهُم مَّغْفِرَةٌۭ وَأَجْرٌ عَظِيمٌ

Innal lazeena yaghud doona aswaatahum 'inda Rasoolil laahi ulaaa'ikal lazeenam tah anal laahu quloobahum littaqwaa; lahum maghfiratunw waajrun 'azeem

The ones who lower their voices in the presence of the Messenger of Allah are those whose hearts Allah has tested for God-fearing. Theirs shall be forgiveness and a great reward.
