Imam Shihab al-Din al-Ramli, as one of the later scholars of the Shafi'i school, has not been the subject of any study analysing the foundational principles of uṣul al-fiqh upon which he based his fatawa. Therefore, this research seeks to address this scholarly gap by revealing the extent of consistency between his juridical rulings and his adopted foundational principles. The researcher employs an inductive methodology to trace the principles of uṣūl al-fiqh in Imam Shihab al-Din al-Ramli's works, subsequently identifying scholarly disagreements that exist regarding these principles and clarifying points of contention among scholars. The research also adopts an analytical approach to examine of Imam Shihab al-Din al-Ramli’s juridical statements, establishing the foundations of these juridical branches under their appropriate usul principles. This study demonstrates the practical implications derived from the science of usul al-fiqh, transitioning it from its theoretical dimension towards practical application in the field of jurisprudence. Consequently, it provides the science of usul with greater clarity and significance, while revealing the sources of disagreement in the differences that occur between earlier and contemporary jurists within the Shaf'i school and other schools of Islamic jurisprudence. The findings indicate that Imam Shihab al-Din al-Ramli bases his juridical opinions on strong, well-established evidence, grounding them in usul principles that align with either the established principles of the Shāfiʿī school or the consensus of the majority of Islamic scholars.arCopyright International Islamic University Malaysia.Master Theses
