The sources show that two different groups of sheikhs were followed in the Hanafi usūl al-fiqh: 'Iraqi and Samarqandi sheikhs. However, the perception of followers of 'Iraqi sheikhs formed the dominant Hanafī tradition. This situation has caused different approaches of the theologian methodologists who followed the Samarqandi sheikhs to become in shadow. Considering this separation within this denomination, when the sunnah sections of usūl alfiqh literature are compared it is possible to see the different points raised within the Hanafi usūl al-fiqh. In this study, "the definition of sunnah", "the acts of the Prophet", "the imitating companions", "the criteria of ard (submission) to the Qur'an" and "the problem of faqīh (jurist) narrator" are determined as differentiated notions. Considering these issues, since the concepts which differentiate theologian methodologists, whose perception have been taken into account in this paper, from the dominant Hanafi usūl tradition have been generally related to theological concerns, it is possible to argue that this distinction can be explained by their approach of usūl in which theological premises considered as important as other concerns. Eventually, this paper aims to show that like any denomination Hanafi sect also does not have a uniform approach about sunnah. Summary: In this study, the marks of differentiations in sunnah topics were followed based on the works of Ḥanafī usūl al-fiqh written in the Transoxanian region between 5th-8th centuries A.H. The reason for the limitation of this issue is that there have been some changes and developments in the sect in this region and period. It is because Ḥanafī usūl al-fiqh, which is in two different lines, namely ʿIrāqī sheikhs and Samarqandī sheikhs, has improved in favor of one side in this period. It is thought that this dual disintegration occurs due to the effect of different theological tendencies. This situation has caused the different approaches of the theologian methodologists who mostly followed the Samarqandī sheikhs to be overshadowed. Because Ḥanafī tradition, which became a permanent establishment, mostly followed the line of ʿIrāqī sheikhs in terms of both the topics that are discussed and the approaches in these issues. The aim of this study is to determine the different approaches of the line of Samarqandī sheikhs to sunnah. In the study which is based on comparative method, sunnah topics of Dabūsī, Pazdawī, Sarakhsī and those who followed them and the theologian methodologists Abū l-Yusr, Samarqandī, Lamishī and Usmendī's sunnah topics were compared and the differ-81
