This course walks students through the process of extracting Islamic rulings, the principles of jurisprudence and legal theory. What are the principles scholars rely on in arriving at Islamic rulings? How do we deal with contradictory hadiths? How do we deal with modern issues, such as cloning, when we have no specific hadith addressing them? What is the Law of Exemption? What is the Law or Continuity? These are some examples of what will be discussed in this class. The primary text for this course will be Principles of Islamic Jurisprudence (Halaqa al-Oula) by Sayed Mohammad Baqer al-Sadr. A total of 46 lessons were presented in the year 2017-2018. This course is instructed by Sayed Mohammad Baqer al-Qazwini.
