Machine translationRead the Arabic original
Question:
He says: What is the ruling on one who memorizes the Qur'an or a surah from the Qur'an and then forgets it? Is this one of the major sins?
Answer:
No, it is not one of the major sins. Forgetting is not by human choice; a person is afflicted with forgetting.[Al-Baqarah 2:286] However, he should keep up with the Qur'an and his memorization and repeat it, because its loss for him would be a loss in his maintenance of it. But if he forgets, that is not a sin; this is a loss of good, a loss of good, and it is not with Shaytan.

Our Lord, do not impose blame upon us if we have forgotten or erred.
رَبَّنَا لَا تُؤَاخِذْنَا إِن نَّسِينَا أَوْ أَخْطَأْنَا
