This topic is written because the concept of qath’i introduced by Ash�Syatibi as contained in his book al-Muwafaqat is different from that
conceptualized by Jumhur scholars. According to ash-Syatibi, that all
fundamental premises (muqaddimah) in legal theory must be something
that is clearly certain (qath’i), and these premises can be rational,
conventional or revelation. In his book it is explained that there is no or
very little verse of the Qur'an that is qath’i, if what is meant there is no
other possible meaning for a while. The concept of qath’i developed by
Ash-Syatibi has contributed significantly to the development of the
science of Usul fiqh. Methodologically, asy-Syatibi developed his legal
theory through inductive reasoning (istiqra’) more broadly which was
previously deductive. With the application of the induction method, the
qath’i-an (certainty) of the meaning of a nashh is obtained through
careful investigation of all Syar'i arguments that contain the same
meaning so that the meaning is no longer zhanni but increases to
mutawatir Ma'nawiyyah and is named qath’i al-Dilalah.
