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."
قَالَ رَسُولُ اللَّهِ ﷺ لَمْ يَأْذَنِ اللَّهُ لِشَىْءٍ مَا أَذِنَ لِلنَّبِيِّ ﷺ يَتَغَنَّى بِالْقُرْآنِ وَقَالَ صَاحِبٌ لَهُ يُرِيدُ يَجْهَرُ بِهِ
