فرائد اللآلئ ليحيى بن عبد الله فخر الدين الرومي في الفقه الحنفي (ت864ه)

This thesis investigated a section of the book "Farad Al-La'ali" which wroted by Sheikh Yahya bin Abdullah Fakhr al-Din al-Rumi: from the Book of Crimes to the Book of the Mufti's ethics. The book is a summary of the fatwas of Hanafi jurisprudence, arranged on the chapters of jurisprudence that collected from the explanations and fatwas. Its importance comes from being specific to issues that people share and need all the time and they ask scholars and specialists about them. It also included strange, rare and controversial fatwas among the Hanafi jurists. The study followed the historical descriptive approach in presenting the biographical and scholarly biographies of the author: Sheikh Yahya bin Abdullah Al-Roumi, and the political, social and educational aspects of his era, while the scientific method used in the investigation and commentary on the book: such as writing the text, justify the text with diacritics, comparing the copies, attributing the sayings, and extracting the issues and documenting them. The most important conclusion of the study was: The author depends heavily on opinion and analogy in the rooting and inference of the researched jurisprudential issues and rarely quotes the Holy Quran and the Sunnah, This confirms that the Hanafi school is based on the principle of reason and analogy as one of the approved principles of the school, this means that the reason is an authentic source of applicable Islamic legislation, as well as the creativity of Sheikh Yahya Al-Roumi in dividing the book into chapters, and put the issues into sections to make it easier to benefit from it, Likewise, the author has a superior ability to cite the sayings and weighting them with evidences. He was also fluent in the Persian language, as he used to mention many of the jurist's fatwas in it. Finally: The Sheikh left many important fatwas on many issues, such as: marriage, divorce, lineage, treatment of people of other religions, apostasy, and inheritance, in a way that benefits specialists, students and Judicial and legislative specialists.
