assets of the classical texts of our pious predecessors and the integrity and credibility of their authors call for particular and due efforts, accurateness and reflection in the rewriting, modification and writing of textbooks.

On the other hand, the change and transformation in the orientations, needs, expectations, methods, and models in training and education, multiply the responsibilities of the administrators and officials dealing with education and research affairs as well as academic planning in the Islamic seminary, as they have to perform their functions constantly by presenting new and original categories, patterns and frameworks and by improving the substance of textbooks.

As such, on the basis of the abovementioned needs and concerns, Al-Muṣṭafā International University has embarked on reviewing, modifying and producing textbooks, thereby typesetting, compiling and publishing hundreds of titles.

Along this line, while keeping the originality and substantial richness of the surviving precious treasures of the past scholars and by utilizing the educational technology and observing the modern principles, standards and patterns, it strives to present texts compatible with the objectives and within the framework of the approved programs and subjects, intellectual level, and expectations of the students.

Walking along this long and winding road necessitates the all-out support and cooperation of the esteemed professors, experts, academic directors, and students. By offering their suggestions, criticisms and opinions, they could help us in correctly and successfully treading this difficult and tortuous path.

We take this opportunity to express our utmost gratitude to those who have done their best to bring this project
