Tajweed is the proper pronunciation of words. All Muslims should Learn Quran with Tajweed. The statement ‘learn Quran with Tajweed’ therefore means that a Muslim student who wishes to learn how to read the Quran will pronounce the Arabic words the way that they are supposed to be pronounced. Islam is a religion that has spread widely all over the world even to the non-Arabic countries. This should not be an excuse of pronouncing the Arabic words wrongly. One should aim at learning to pronounce the sound the way they were originally pronounced to Prophet Mohammed.
When the prophet Mohammed wrote the Quran in Arabic, he wrote each and every word the way they were recited to him by the archangel Gabriel. He did not assume any pronunciation from the arch angel. This was a very holy process of passing the holy book to them. They are therefore under no obligation to assume the pronunciation of the holy words from the holy book.
One of the Tajweed rules and regulations when reading the Quran is that recitation of the Quran should be done with all care. It should be done with knowledge and skill learnt in the madrasas. Learning how to read and recite the Quran surasforms a major part of the classes in the study of the Quran. The tutor should aim at making the students be able to pronounce the Quran the way the holy prophet Mohammed recited them directly from the arch angel.
Allah who is the Islam god will always bless anybody who recites the Quran correctly the way it was intended from the beginning. Curses are associated with one who does it without Tajweed especially if they do it knowingly. Tajweed classes therefore form a major part of learning how to read the Quran.
