Question:
What is the punishment for one who forgets the Noble Qur'an, and when is a person excused for that?

Answer:
There is no blame on him for that if it was not by his choice. As for one who forgets the Noble Qur'an as a result of negligence and failing to maintain its recitation, he has suffered a great loss due to his negligence and lost much good. As for one who relies on forgetting, that will lead to that, but we say that he has lost a great blessing and suffered a great loss. The Prophet (peace and blessings be upon him) advised to keep reviewing this Qur'an, stating that it is more likely to slip away or be lost than camels in their pens. This indicates that the portion of one who memorized the Qur'an is to keep reviewing it by recitation, and that at least a month should not pass without him having completed the recitation of the Qur'an. If he recites it in less than that, it is better.
