Likewise, correcting ones recitation firstly and not depending on oneself in its recitation even if one is knowledgeable of the Arabic language and of its principles, is also obligatory. This is because in the Qur'an there are many verses which occur in a way that is opposed to what is well known in the rules of the Arabic language. It is necessary for the one desiring to memorize the Qur'an that he sets himself a daily limit for memorizing. So he begins, after he has corrected his recitation and set his daily limit, to learn by frequent repetition. It is also necessary that this repetition is done melodiously and this is so that a person follows the Sunnah firstly and that it the memorization is made firm and strong secondly.
Melodious recitation is pleasing to ones hearing and also assists in memorization.
The reciter will know therefore, that his tongue will not comply with him when he makes a mistake and that if the tone is wrong or out of tune, his memorization will return to him. All of this is because reciting the Qur'an and beautifying it with ones voice is a mastronger which has been commanded. Not Surpassing One's Daily Limit until You Have Perfected its Memorization. It is not permissible for the memorizer to move to a new portion of the Qur'an until after he has perfected the memorization of his previous limit. This is so that whatever he has memorized is firmly established in his mind.
