Messenger of Allah ﷺ said, "Allah does not listen to a prophet as He listens to a prophet who recites the Qur'an in a pleasant tone." The companion of the sub-narrator (Abu Salama) said, "It means, reciting it aloud." (Using translation from Bukhārī 5023)
قَالَ رَسُولُ اللَّهِ ﷺ «لَمْ يَأْذَنِ اللَّهُ لِشَيْءٍ مَا أَذِنَ لِنَبِيٍّ يَتَغَنَّى بِالْقُرْآنِ» قَالَ صَاحِبٌ لَهُ أَرَادَ يَجْهَرُ بِهِ
