Magister Artium - MA / This study examines the foundations of the various methods of identifying legal cause (masālik al-ʿillah). It studies its various theories, spanning the classical and premodern period and investigates its application in contemporary times. The investigation analyses the theories of masālik al-ʿillah while placing the legal cause (ʿillah) contextually within the convention of analogical reasoning (qiyās). The findings of this investigation are then used to study practical applications of identifying legal cause, in a selection of three case constructions of qiyas, under the topic of suicide attacks.
