Praise be to Allah Whom we worship and to Whom we pray for help, from Whom we seek protection from the evil of our souls and our evil deeds. Whoever Allah guides to a straight path, none can misguide, and whoever He misguides, none can guide. I testify that there is no god except Allah, Who has no companion, and that Muhammad is His slave and Messenger (blessings and peace of Allah be upon him).

And then:

The Quran is the Word of Allah Almighty, which was given to our Prophet Muhammad (peace and blessings of Allah be upon him) in clear Arabic through the angel Jibreel (peace be upon him) and reached us through transmission from the first generation to later generations.

The Quran is the greatest miracle that will remain so until the Day of Judgment, and which Almighty Allah has taken upon Himself to protect, He ( May He be praised and exalted) said:

«It is certainly We Who have revealed the Reminder, and it is certainly We Who will preserve it.» (surah al-Hijr, 9 verse).

Ten awards are recorded for each letter that has been read from the Holy Quran. The one who has learned one verse of the Quran is awarded every time they recite it. Those who study the Qur'an and follow it are chosen by Allah and are the closest people to Him.

Allah has prepared the greatest of all kinds of rewards for reading, studying and memorizing the Quran, as reported in numerous hadiths by the Messenger of Allah (peace and blessings of Allah be upon him).

Uthman ibn Affan reported that the Messenger of Allah (peace and blessings of Allah be upon him) said:

«The best among you (Muslims) are those who learn the Qur'an and teach it» (Al-Bukhari).

Abdullah ibn Mas’ud (may Allah have mercy on him) reported: The Messenger of Allah (peace and blessings be upon him) said:

«Whoever recites a letter from the Book of Allah, they will receive one good deed as ten good deeds like it. I do not say that Alif Lam Mim is one letter, but rather Alif is a letter, Lam is a letter, and Meem is a letter.» (Sunan al-Tirmidhī, 2910).

Anas (may Allah be pleased with him) reported: The Messenger of Allah (peace and blessings be upon him) said:

«Indeed, Allah has His own people from among humanity! He was asked: “Who are they, O Messenger of Allah?”, he replied, “Ahlul-Quran (those who read and study the Quran)! They are the close people of Allah and His chosen ones!”» (Ahmad).

It is the duty of every Muslim to read the Quran according to the rules and without mistakes. The main and most important duty for a Muslim person are the five daily prayers, which will be considered invalid if the rules of reading are not followed. Because Almighty Allah commands:

وَرَتِّلِ الْقُرْآنَ تَرْتِيلًا
or a little more—and recite the Quran [properly] in a measured way.
Surah 73 al-Muzzamil, аят 4

Measured reading (tarteel) is the reading in which all the rules of Tajweed are followed.

Ali ibn Abi Talib (may Allah have mercy on him) said in the explanation of this ayah:

«at-Tarteel is Tajweed of the letters and knowing where to stop (correctly)» (Ibn al-Jazariy).

In this verse, Allah commands that we recite the Quran according to the rules of tajweed.

Tajweed is theory and practice, and therefore one should have a teacher while studying it. Even if people are able to study the rules, their correct application can only be done by listening to, reciting to, and being corrected by, a competent teacher of the Quran. Therefore, it is better to study and practice with qualified teachers.

The rules of tajweed are necessary so that a person can read the holy Quran eloquently and without mistakes, as our Prophet (peace and blessings of Allaah be upon him) did.
