Sunan an-Nasa'i 1663

أَخْبَرَنَا هَارُونُ بْنُ مُحَمَّدِ بْنِ بَكَّارِ بْنِ بِلاَلٍ، قَالَ حَدَّثَنَا مُحَمَّدٌ، - يَعْنِي ابْنَ سُمَيْعٍ - قَالَ حَدَّثَنَا زَيْدٌ يَعْنِي ابْنَ وَاقِدٍ، عَنْ كَثِيرِ بْنِ مُرَّةَ، أَنَّ عُقْبَةَ بْنَ عَامِرٍ، حَدَّثَهُمْ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ إِنَّ الَّذِي يَجْهَرُ بِالْقُرْآنِ كَالَّذِي يَجْهَرُ بِالصَّدَقَةِ وَالَّذِي يُسِرُّ بِالْقُرْآنِ كَالَّذِي يُسِرُّ بِالصَّدَقَةِ ‏"‏ ‏.‏

It was narrated from Kathir bin Murrah that 'Uqbah bin 'Amir told them that:The Messenger of Allah (ﷺ) said: 'The one who recites the Qur'an loudly is like one who gives charity openly, and the one who recites the Qur'an silently is like the one who gives charity in secret
