The Holy Qur’an is easy to understand and remember. Allah says in the Qur’an: “We have indeed made the Qur’an easy to understand and remember.”
Many Muslims memorize the Quran, or part of the Qur’an. There is great reward promised to those who memorize the surah, the chapters, of the Quran. The blessed Prophet Muhammad [s] used to encourage his Companions to memorize as much of the Qur’an as possible. A person who has memorized the Qur’an is called a Hafiz of Qur’an.
