She vowed to memorize the Qur'an if she became a teacher, but she was unable to do so. What is she required to do?

Question:
I made a vow to myself that if I became a teacher, I would memorize the entire Qur'an. I said this without knowing what this word entailed, and I was lax in my regard for it. When I entered the institute, and now, praise be to Allah, I have become a teacher, I remembered my vow. I realized that I cannot do it because I memorized a portion and then forgot most of the surahs. My memory is weak, and it requires daily or at most weekly review. My time has become tight. I know that one who vows to obey Allah must obey Him, but I was unable to. I will try to obtain some images and some portions. My question now is: what should I do? Should I fast days or give charity? I am able to do so. Please guide me to an action other than memorization that I can perform. May Allah reward you with good.

Answer:
Memorizing the Noble Qur'an is an act of worship and obedience to Allah (Glorified and Exalted is He). As the questioner mentioned, and as stated in the hadith , you must fulfill this vow, which is to attempt to memorize the Noble Qur'an. There is good in that for you, if Allah wills. So you must try. Attempt it, memorize the Qur'an, seek help from Allah (Mighty and Majestic), and organize your time for memorization. Even if you memorize a small amount each day, with continuity, follow-up, and repetition, by the permission of Allah, you will achieve the memorization of the Qur'an, with the assistance of Allah (Glorified and Exalted is He). This is not a miraculous or impossible matter, but rather something that is easy. However, the matter lies in the direction, the establishment, and the sincerity of the intention. And Allah the Exalted says: So you must memorize the Qur'an, even if it involves some hardship for you, but with practice and organization, this hardship will disappear.
If Allah wills, may Allah reward you with good. So memorization is necessary, and there is nothing else. Memorization is necessary because it is not impossible. If Allah wills, may Allah reward you with good.
