الحجرٰت — Al-Hujurat Ayat 3
اِنَّ الَّذِيْنَ يَغُضُّوْنَ اَصْوَاتَهُمْ عِنْدَ رَسُوْلِ اللّٰهِ اُولٰۤىِٕكَ الَّذِيْنَ امْتَحَنَ اللّٰهُ قُلُوْبَهُمْ لِلتَّقْوٰىۗ لَهُمْ مَّغْفِرَةٌ وَّاَجْرٌ عَظِيْمٌ
Innal-lażīna yaguḍḍūna aṣwātahum ‘inda rasūlillāhi ulā'ikal-lażīnamtaḥanallāhu qulūbahum lit-taqwā, lahum magfiratuw wa ajrun ‘aẓīm(un).
"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."
