Özet:

In the second period of the Shāfiʿī school, Ebü'l-Mehâsin al-Rūyānī is one of the important figures who grew up in the hijrī 5th century. Rūyānī, who took lessons from many Shāfiʿī scholars while traveling to the important science centers of the period, gained a deep knowledge of the Shāfiʿī school. Rūyānī, known as the Shāfiʿī of the time, trained many scholars by giving lectures in madrasahs and mosques. In addition, he made important contributions to the development of Shāfiʿī school by making studies on Shāfiʿī fiqh. The most striking among these works is Baḥr al- madhhab fī furūʿi madhhab al-Imām al-Shāfiʿī. In the work, which has achieved the fame it deserves by surpassing the fame of its author, the opinions of other sects are also included, as well as the conflicts within the school. In this sense, the work has gained the quality of a comparative study both within and between sects. In our article, after a short biography of Rūyānī, his work Baḥr al- madhhab has been examined from different perspectives. In this context, after mentioning the broad outlines of the content and classification of the work, we try to determine the sources he used and the method followed in the work. Then the position of the work in the school is also discussed.
