Surah Al-Hujurat — Ayah 3 (49:3)
إِنَّ ٱلَّذِينَ يَغُضُّونَ أَصۡوَٰتَهُمۡ عِندَ رَسُولِ ٱللَّهِ أُوْلَٰٓئِكَ ٱلَّذِينَ ٱمۡتَحَنَ ٱللَّهُ قُلُوبَهُمۡ لِلتَّقۡوَىٰۚ لَهُم مَّغۡفِرَةٞ وَأَجۡرٌ عَظِيمٌ ٣
English translation (Saheeh International)
Indeed, those who lower their voices before the Messenger of Allāh - they are the ones whose hearts Allāh has tested for righteousness. For them is forgiveness and great reward.
Brief commentary
Indeed, those who lower their voices near the Messenger of Allah (peace be upon him), they are the ones whose hearts Allah has examined for His consciousness, and chosen them for it. For them is forgiveness for their sins; they will not be accounted for them, and they will receive a great reward on the Day of Judgement, which will be that Allah enters them into Paradise.
