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

وَعَنْ عُقْبَةَ بْنِ عَامِرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الْجَاهِرُ بِالْقُرْآنِ كالجاهر بِالصَّدَقَةِ ولامسر بِالْقُرْآنِ كَالْمُسِرِّ بِالصَّدَقَةِ» . رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَالنَّسَائِيُّ وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ
