What are the specific reasons for preserving the Qur'an?

The questioner : May Allah preserve you, O honorable Shaykh. What are the specific reasons that help in preserving the Qur'an?

The Shaykh : The most important thing, may Allah bless you, regarding the preservation of the Qur'an or other texts is for a person to memorize them while he is young, because memorization in youth is faster and more lasting. Then another thing is that he should devote himself to what he wants to memorize, meaning he should not be occupied with other things. Thirdly, he should review what he has memorized, because some people memorize and move on, but they do not review what has passed, and then they forget it. For this reason, the Prophet (peace and blessings be upon him) commanded the review of the Qur'an and said: These are three things that are among the most important factors in helping to preserve the Qur'an. Know that people differ greatly in the speed of memorization and the speed of forgetting. The best of them is the one who is quick to memorize and slow to forget.
