" الْجَاهِرُ بِالْقُرْآنِ كَالْجَاهِرِ بِالصَّدَقَةِ وَالْمُسِرُّ بِالْقُرْآنِ كَالْمُسِرِّ بِالصَّدَقَةِ "
It was narrated from 'Uqbah bin 'Amir that the Messenger of Allah said: "The one who recites the Qur'an loudly is like one who gives charity openly, and the one who recites the Qur'an quietly is like one who gives charity in secret."
