How do I avoid forgetting what I have memorized of the Qur'an?

Question : We compare some images from the Qur'an in high school, but when we pass the exams, we also carry what we studied, even though we are in Islamic studies, so what do we accept as such, and what is the solution?

Answer : It appears that you memorize the Qur'an but do not review it, except only at the time of the exam. The Qur'an requires that a person always review it. The one whom Allah blesses with the memorization of some of the Qur'an should review it, because the Messenger of Allah (peace and blessings be upon him) said, "Review the Qur'an." The solution for you is that when you finish the exam, you review what you have memorized, reading it and repeating it as much as is easy for you. As for leaving it, you will forget it, because the Messenger (peace and blessings be upon him) said: Yes.
