3إِنَّ الَّذينَ يَغُضّونَ أَصواتَهُم عِندَ رَسولِ اللَّهِ أُولٰئِكَ الَّذينَ امتَحَنَ اللَّهُ قُلوبَهُم لِلتَّقوىٰ ۚ لَهُم مَغفِرَةٌ وَأَجرٌ عَظيمٌZafar AnsariThe 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.
