question #3 Sahih Muslim 789b, Book 6, Hadith 268 : What are the consequences of neglecting the recitation of the Qur’an for someone who has memorized it?

” When one who had committed the Qur’an to memory (or who is familiar with it) gets up (for night prayer) and recites it night and day, it remains fresh in his mind, but if he does not get up (for prayer and thus does not recite it) he forgets it.”
