Amongst the various characteristics of the Glorious Qur'an is its being easy to memorize and understand. In this regard, Allah, Most High, says in the Glorious Qur'an,
(And we have indeed made the Qur'an easy to understand and remember. then is there any that will receive admonition?)
The words and verses of the Glorious Qur'an are distinguished by fluency, sweetness, and simplicity. Therefore, the person who desires to memorize the Qur`an finds it so easy to do so. By the same token, we- see thousands of Muslims, mostly children, memorizing the Glorious Quran. No other book, holy or secular, could surpass the Glorious Qur'an in this respect. Christians, for example, do not memorize the Gospels. Their monks and priests, however, do not memorize half or one-forth of, it let alone the common men.
