Dari al-Syāfiʿī (w. 204 H) ke al-Jābirī (w.1431 H)

This article describes the contribution of bayānī reasoning contained in the Risālah by Muhammad ibn Idrīs al Syāfiʿī. Bayānī reasoning in this context refers to the conceptualization of epistemology of Islamic science proposed by Muhammad 'Abid al-Jābirī. Through the descriptive-analytic method, the author examines a number of literatures related to the epistemology of science and discusses them with al-Risālah, because the relationship between this book and the epistemology of science has never been done. It is concluded that: First, bayānī reasoning in al-Jābirī's epistemological category is etymologically and methodologically related to the term bayān contained in the Risālah. Second, the source of knowledge used by al-Syāfiʿī in al-Risālah refers to the process of transmitting knowledge based on the narration of a narrator. This is like the basic character of Muhammad Abid al-Jābirī's bayānī epistemology which makes the text the source of knowledge. The text taken as a source of knowledge begins with the transmission of knowledge through the narration of a narrator.
