The factors that help in retaining the Noble Qur'an after memorizing it

Question:
May Allah reward you, Your Eminence, father. The questioner says: I have memorized the Qur'an but have not completed it, yet every time I memorize a portion, what I had memorized before it is lost. How can I preserve it with retention and precision?

Answer:
You must seek help from Allah and increase your recitation of the Qur'an and repetition of your memorization until it becomes firm. You must increase your repetition of your memorization until it becomes firm. The Prophet (peace and blessings be upon him) encouraged this and said: "Keep reviewing this Qur'an, for it is more likely to slip away than camels in their pens." You must keep reviewing your memorization until it becomes firm. Seek help from Allah the Exalted. Yes.
