Question

In aayah 4 of Surat-al-Muzammil, Allah subHanahu wa ta'aala says: . Does this mean to read the Qur'an with tajweed?

Answer

It has been said that Ali, may Allah be pleased with him, when asked about the fourth ayaah in Al Muzzamil said:  “It means tajweed of the letters and knowledge of the Waqf.”  We know then that tajweed is part of tarteel, but also knowledge of the different types of stops is necessary to complete the application of tarteel. This statement of Ali, may Allah be pleased with him, cannot be properly authenticated.

Question

How can I learn tajweed on the Internet?

Answer

You can pick up knowledge of the rules of tajweed on the Internet, but applying the rules needs to be done with a trained teacher who listens to you, and corrects you.  This is best done face to face, in a classroom situation.  It may be that Allah makes a way for a teacher to listen and comment on students’ recitation on this site in the future, but at this time, it is not available.
