he general linguistic meaning of Tajweed is "excellence and precision." In specific Islamic terminology it is defined as: "the recitation of the Qur'an as it was revealed to Muhammad, the Messenger of Allah (blessings and peace be upon him)," or more specifically, "giving every letter its right," i.e. observing its correct pronunciation and special qualities, as well as proper length, appropriate assimilation, etc. Learning Tajweed is particularly difficult for nonArabic speakers or new Muslims. However, this book, by Um Muhammad, gives a brief but thorough explanation of the rules of Qur'anic recitation. She also includes a simple diagram of the mouth and throat to illustrate where the sounds of Arabic letters originate. This is a must for anyone studying or memorizing the Qur'an.
