Abstract
Differences in legal issues are closely linked to the differences in isnad (chain of narrators) and mutun (texts of the narration) of Ahadith. There may be numerous causes of these differences, such as tafarrud (uniqueness) of a narrator; relating the meaning and sense of the narration (al-Riwayah bi al-Ma'na), or Wahm (erroneous impression) of the narrator. These differences can be resolved when all the turuq (routes) of the narration are gathered. Imam al-Shafi’i, Imam Ibn Qutaybah and Imam Tahawi are amongst those scholars who have authored books in this field of Islamic sciences. Erroneous impression of the narrator is one of the important causes of difference in isnad and mutun of Ahadith, which is also the subject of this paper. This paper focuses on the erroneous impression of a trustworthy narrator Imam Sufyan b. ’Uyaynah through his narrations and tries to examine the narrations, in which he has disagreed with other trustworthy narrators due to his erroneous impression. Similarly, this paper also examines the nature of impact, which this disagreement has put on the jurisprudential issues.
