Abstract:

This study deals with the life and scholarly personality of Abū Yūsuf this one of the most important three imams in the doctrine and deals with his views these differing from Abū Ḥanīfa and Muḥammed b. el-Ḥasan al-Shaibānī these the other two imams in the in matters of worship. Abū Yūsuf is not only the second founder İmâm of the Hanafi school, but also the teacher of Muḥammed al-Shaibānī, the third important imam and the writer of the school. Therefore, Abū Yūsuf can be considered as the most important figure establishing the Ḥanafi school and moving it to the present time. Because he participated into Mālik’s lecture rings of hadish in Madina, and because Aḥmad b. Ḥanbal participated into his lecture rings in Baghdad, Abū Yūsuf acted as a bridge between the doctrines. It can be stated that his authority in hadith field in addition to the jurisprudence recognized by the leading scholars, gained more respect for the doctriner. The article dealt with fifteen issues in which Abū Yūsuf differed from the other two ımams in the field of worship. The source of the difference in these issues was mostly the following: the difference in the interpretation of the texts of the Sharia, the differenced in the preference between different ḥadīths, or different narrations of one ḥadīth, the difference in the point of view in the essence of the topic and the parties' using of different analogies (qiyās). If we look at the position of other fiqh schools on these issues; It appears that they are at the same distance from both Abū Yūsuf and the other two imâms.
