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.
Abū Dāwūd and Dārimī transmitted it.
