This book is a translation, explanation, and commentary of many foundational Rules of Fiqh. The knowledge of Islam is vast, and the details of Islamic Jurisprudence are extensive. There are so many methodologies in interpreting the guidance from the Quran and Sunnah, the tools utilized in extracting the verdicts, the massive quantity of issues, and the variety of opinions are so copious that it is impossible for most people to know them all. The concept of "Foundational Rulings" (AlQawaid AlFiqhiyyah) is an attempt to simplify the big picture of the Deen. Equipped with this knowledge and Maqasid AshShari'ah AlIslamiyyah (goals and objectives of the Shari'ah,) one can have a bird's eye view of Islam. These foundational rulings are a way to approach Islamic jurisprudence that simplifies the big picture of Islam. They are the "bones" of Islamic law. The foundational rulings are based on the Quran and Sunnah, and they are the basis for all Islamic law. They are the framework of Islam, and they are necessary to understand and apply Islamic law.
