Mishkat al-Masabih 2105

‘Uqba b. ‘Āmir reported God’s messenger as saying, “He who recites the Qur’ān loudly is like him who gives sadaqa openly, and he who recites the Qur’ān quietly is like him who gives sadaqa secretly.” Tirmidhī, Abū Dāwūd and Nasā’i transmitted it, Tirmidhī saying this is a hasan gharīb tradition.
