There are many benefits to the knowledge of 'uloom al-Qur'aan. Firstly
, it enables the reader to realise the wealth of knowledge and insight that exists with regards to the Book of Allaah سبحانه و تعالى. As some of the scholars of the past said, "True knowledge is to know one's ignorance." Only when a person realises what he does not
know will he appreciate what he does
, it enables the student of knowledge to better understand the Qur'aan, in that he will be familiar with the history of its revelation and collection, and the various aspects that aid its comprehension. When he reads the books of tafseer
, he will be able to understand the terms used, and benefit from the knowledge in them to a greater extent. In other words, he will be quipped to further increase his knowledge and to learn more about his religion. Thirdly
, it increases a person's belief (eemaan
), because he will realise the beauty of the Qur'aan and the great blessings that he has been given through its revelation. He will not be fooled by the fallacious claims of its enemies, and his heart will be at ease with regards to its authenticity. He will understand the miraculous nature of the Qur'aan, and thus better cherish the greatest Book that mankind has been given. Fourthly
, he will be able to defend the Qur'aan against its enemies, since he will be equipped with the true and pristine knowledge of the Qur'aan, unadulterated by the prejudices of its opponents.
It is no exaggeration to say that, once a person learns the essentials of his religion and what is required for him to know, the first knowledge he should turn his attention to is the knowledge of the Qur'aan and its sciences. As Allaah سبحانه و تعالى says  in the Qur'aan, "(This is a) Book that We have sent down to you, full of blessings, so that they may ponder over its verses, and that men of understanding may remember."
(Soorah Saad: 38:29)  Notes:
 It should be pointed out that the Qur'aan is only in Arabic, and is the speech (kalaam) of Allaah سبحانه و تعالى. Therefore, the unconditional phrase, "Allaah says," when used, only refers to the Qur'aan. When this phrase is used in a language other than Arabic, it contains an additional implicit clause that should be understood by the audience, and this clause is, "the meaning of which is," since the Qur'aan is only in Arabic. Therefore, the phrase should be understood as, "The meaning of what Allaah has said is..."
