Memorizing the Qur'an is not something that can be said as an easy thing, but more. A person who intends to memorize the Qur'an certainly has many problems. So most people who initially intend to learn the Qur'an but after experiencing various difficulties, ultimately prefer not to continue remembering the Qur'an. To deal with this problem, a memorizer of the Qur'an is recommended to perform multiple penances, one of which is fasting in the Qur'an. The method used is descriptive analysis, so the final result is that fasting in the Qur'an is one of the most effective ways to memorize the Qur'an for the students.
