The Qur’an was revealed with Tajweed rules applied to it. In other words, when the angel Jibreel ((AS)) recited the words of Allah to the Prophet Muhammad (SAW) he recited them in a certain way and he showed the Prophet (SAW) the ways in which it was permissible to recite the Qur’an. So it is upon us to observe those rules so that we recite it in the way it was revealed.
The purpose of Tajweed
The Qur’an is the word of Allah, and its every syllable is from Allah. Its recitation must be taken very seriously. The purpose of the Science of Tajweed in essence is to make the reciter proficient in reciting the Qur’an, observing the correct pronunciation of every letter with the rulings and characteristics which apply to each letter, without any exaggeration or deficiency.
