It was narrated that ‘Abdur-Rahman bin Sa’ib said:
“Sa’d bin Abu Waqqas came to us when he had become blind. I greeted him with Salam and he said: ‘Who are you?’ So I told him, and he said: ‘Welcome, O son of my brother. I have heard that you recite Qur’an in a beautiful voice. I heard the Messenger of Allah ﷺ say: “This Qur’an was revealed with sorrow, so when you recite it, then weep. If you cannot weep then pretend to weep, and make your voice melodious in reciting it. Whoever does not make his voice melodious, he is not one of us.”

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ أَحْمَدَ بْنِ بَشِيرِ بْنِ ذَكْوَانَ الدِّمَشْقِيُّ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنَا أَبُو رَافِعٍ، عَنِ ابْنِ أَبِي مُلَيْكَةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ السَّائِبِ، قَالَ قَدِمَ عَلَيْنَا سَعْدُ بْنُ أَبِي وَقَّاصٍ وَقَدْ كُفَّ بَصَرُهُ فَسَلَّمْتُ عَلَيْهِ فَقَالَ مَنْ أَنْتَ فَأَخْبَرْتُهُ . فَقَالَ مَرْحَبًا بِابْنِ أَخِي بَلَغَنِي أَنَّكَ حَسَنُ الصَّوْتِ بِالْقُرْآنِ سَمِعْتُ رَسُولَ اللَّهِ ـ ﷺ ـ يَقُولُ " إِنَّ هَذَا الْقُرْآنَ نَزَلَ بِحُزْنٍ فَإِذَا قَرَأْتُمُوهُ فَابْكُوا فَإِنْ لَمْ تَبْكُوا فَتَبَاكَوْا وَتَغَنَّوْا بِهِ فَمَنْ لَمْ يَتَغَنَّ بِهِ فَلَيْسَ مِنَّا " .
