(44) باب قَوْلِ اللَّهِ تَعَالَى {وَأَسِرُّوا قَوْلَكُمْ أَوِ اجْهَرُوابِهِ إِنَّهُ عَلِيمٌ بِذَاتِ الصُّدُورِ أَلاَ يَعْلَمُ مَنْ خَلَقَ وَهُوَ اللَّطِيفُ الْخَبِيرُ}
Narrated Abu Salama:
Abu Huraira said, "Allah's Messenger (ﷺ) said, 'Whoever does not recite Qur'an in a nice voice is not from us,' and others said extra," (that means) to recite it aloud."
