Sā‘d b. Ubāda reported God’s messenger as saying, “Every man who recites the' Qur’ān and then forgets it* will meet God on the day of resurrection in a maimed condition.”
*This has been explained as referring to one who has learned the Qur’ān by heart and later forgets it, or neglects to recite it.
‘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.
