1. Topic Focus: this is the most important characteristic in this school. Unlike other Islamic lecturers, Al-Waeli concentrates only on one subject in each lecture and does not branch out to different subjects. The purpose of this is to avoid confusing and losing the audience’s attention, and to provide enough details to cover the subject. This is not an easy task. In fact, it requires a big effort from the lecturer to study the subject thoroughly before lecturing to make sure that all aspects of the topic are covered. Besides, he starts his presentation with a short statement that describes the focus of his lecture. This statement is usually a verse from the Qur'an.
