What should a female reciter of the Qur'an do who has forgotten most of it due to lack of review, and is it sufficient for her to merely continue reciting?

Forgetting the Qur’an is negligence and a sin. We advise you to persevere in daily revision and to set a schedule for that, in order to fully and perfectly retrieve your memorization, especially during the night prayer. Do not content yourself with recitation without memorization by heart, according to the Hadith (definition): "The one who is proficient with the Qur’an will be with the noble and righteous scribes (angels)." Seek Allah’s help and be keen to recite to some female Qur’an teachers, and beware of laziness and negligence.
