In order for the person to be rewarded by Allaah سبحانه و تعالى for his recital and in order for the reader to maximise his guidance from the Qur'aan he must make his intention such that he is not reading the Qur'aan for any worldly benefit. Instead, he must read it solely for the sake of Allaah سبحانه و تعالى, to please Allaah سبحانه و تعالى and to get His guidance. This must be something clear in his conscience before he begins his reading of the Qur'aan.
The Messenger of Allaah صلى الله عليه وسلم said, "Surely, all actions are but driven by intentions and, verily, every man shall have but that which he intended." [1]
Shaykh Salaahud-Deen Al-Khaalidi notes, "The knowledge, understanding and pondering over the Qur'aan is a pure blessing from Allaah سبحانه و تعالى and a mercy from Him. And the mercy of Allaah سبحانه و تعالى is not granted to someone whose heart is filled with confusion, deception and deceit." [2]
The question of a proper intention is of extreme importance with respect to every act of worship. However, it is of special importance with respect to reading and memorising the Qur'aan. This is because memorising the Qur'aan or reading it in a beautiful voice is often an act for which one becomes well-known. In other words, the word spreads quickly that a specific person has a beautiful recitation or has memorised so much of the Qur'aan. Therefore, it is relatively easy for Shaytaan to come to such a person and affect his intention. Instead of reading and learning the Qur'aan for the sake of Allaah سبحانه و تعالى, to some extent his learning and reading is being done for the sake of show and the accolades that he is receiving from the Muslims around him.
The Prophet صلى الله عليه وسلم alluded to this fact when he said, "Certainly, the majority of the hypocrites [in their deeds] from among my Nation (Ummah) are its Quranic reciters (Qurraa'uhaa)." [3]
