based on the methodology established by the imam - founder of an Islamic mazhab - or based on the rules
that have been established by the followers of the mazhab and accepted as valid methods of deducing
laws in the mazhab. This article aims to study the historical development of ijtihad within the scope of a
mazhab - Takhrij al-Furuʻ ʻala al-Usul. The focus of the research will be on the definition of Takhrij alFuruʻ ʻala al-Usul, its importance, its historical development and its role in deducing Shariah rules
within the sphere of the mazhab. The study found that Takhrij al-Furuʻ ʻala al-Usul is a method that has
been used by scholars of the mazhab to derive a hukum. It has contributed greatly in expanding the
mazhab, deducing the laws within the boundary of the mazhab and ensuring that Shariah laws founded by
the mazhab remain relevant in facing the changing of time and situations.based on the methodology established by the imam - founder of an Islamic mazhab - or based on the rules
