An Unknown ？abaqāt From The Third Century ？umayd b. Zanjūya’s (d. 251/869) Work Entitled ？abaqāt al-Fuqahā’ wa-al-Mu？addithīn

？umayd b. Zanjūya (d. 251/869), who was born in Nasā/Khorasan during the third century of hijri, is one of the most significant scholars of hadith. Still, only three manuscripts of all ？umayd b. Zanjūya’s works published from the third century onwards are about ？abaqāt and have been positively identified to have been written by him. These are Kitāb al-Amwāl, Kitab at-Targhīb and Kitāb al-ādāb. The Kitāb al-Amwāl is recognized as mustahraj, which was composed using the identical title as the book of his teacher Abū ‘Ubayd Qāsim b. Sallām (d. 224/838), has reached us in the contemporary times and has been successfully edited and published. His other two works, which unfortunately have not reached us in the present times, have been identified from all the other sources and from the hadith narrations. In this article, the author has put emphasis on a book of ？abaqāt, which previously had not been identified nor had it been mentioned in the ？abaqāt, rijāl and biography sources, but thorough research it has been discovered that it can be traced back to ？umayd b. Zanjūya. This book with the title of ？abaqāt al-fuqahā’ wa-al-mu？addithīn was published by Dār Ibn ？azm publishings by R？dwān el-Hasrī who meticulously worked on it by basing it on a copy that is at the present in the Library of Ibn Yūsuf in Morocco, Marekesh. In it there are assessments made about it possibly being the work of ？umayd b. Zanjūya due to the work’s properties, its content and its place among the ？abaqāt sources. This source has been acknowledged for its place and importance in other opuses within the tabakat works which have not reached the present time. The only copy of the work that survived to the present day is missing its title and last part of the book. We cannot identify the name of the work neither from the present copies nor from the sources. The name ？abaqāt al-fuqahā’ wa-al-mu？addithīn was adopted by the researcher (mu？aqqiq). The content of the work of the fuqahā’ and mu？addiths are included separately in the layers and the fact that al-Haysam b. ‘Adī’s (d. 207/822) ？abaqāt al-fuqahā’ wa-al-mu？addithīn, which has not survived to the present, is among the written sources referenced within this work makes it apt for this title to have been bestowed upon this work. We have been able to establish the author of the work from the phrase “？umayd said” in two places and from the narrative in the work. It is also based upon the fact that fifteen of the nineteen names narrated in the work happen to be Zanjūya’s teachers who he narrated specifically in Kitāb al-Amwāl, which as stated
