The book is distinguished from other tajweed books and letters in circulation in that it is suitable for the modern learner, enabling him to fulfill the obligation of applying the rules of tajweed while reciting the Holy Qur'an and saving him from the confusion that prevents him from recalling the rules and applying them to read well, which results from the accumulation of the many tajweed rules in the mind of the reader and the difficulty or impossibility of applying them.
