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

Surely those who lower their voices before Allah's Apostle are they whose hearts Allah has proved for guarding (against evil); they shall have forgiveness and a great reward.
