Treating the Forgetting of the Qur'an When Memorizing It

Question:
You have here an issue that is frequently asked about, which is that some of the brothers say that he tries to memorize the Book of Allah the Exalted, but he forgets it. What is the treatment for this? May Allah reward you.

Answer:
And he should be optimistic about good, and he should avoid [sin] even if he forgets; he should not despair, he should not rush, he should preserve a little, a little, a little, a little, and he should be optimistic about good. Even if he forgets, his forgetfulness does not harm him, for it was not by his choice. Allah, Exalted and Majestic, said: "And indeed, We have taken a covenant from all the children of Adam: 'Do not associate anything with Me,'" and the heart forgot, and in the hadith it is narrated from him that he said, (peace and blessings be upon him): And Allah says: "Whoever forgets, if we have made a mistake, then Allah says: 'You have done as you said,'" as narrated by Muslim in the Sahih. But he should strive and ask his Lord for success, and he should be optimistic about good, if Allah wills.
