and Taqī al-Dīn al-Subkī (d. 756 AH), ʿAlam al-Dīn al-Barzalī (d. 739 AH), and Shihāb al-Dīn al-Nābulusī (d. 758 AH) (1), all of them eminent ḥuffāẓ, traditionists, and historians. He further noted that the hadith scholars of his own day were, in the science of rijāl and the other branches of hadith, dependent on four authorities—one of whom was al-Dhahabī (2).

Although al-Dhahabī’s historical brilliance showed itself most clearly in his treatment of individual transmitters, he also studied political history and produced abridgements of a number of its major works, such as the History of Abū Shāma (d. 665 AH) and the History of Abū al-Fidāʾ (d. 732 AH), among others. He profited from—and carefully examined—nearly every chronicle known in his time, including the Sīrah of Ibn Isḥāq (d. 151 AH) and the histories of al-Ṭabarī (d. 310 AH), Ibn al-Athīr (d. 630 AH), Ibn al-Jawzī (d. 597 AH), and many more too numerous to list (3).

The fruit of these studies is evident in his own chronicles arranged by events and obituaries, such as Taʾrīkh al-Islām, al-ʿIbar, Duwal al-Islām, and others.

From the breadth of this corpus we see that he was a historian of roaming intellect, able to encompass the entire span of Islamic history—from its very dawn to the period in which he wrote, well over seven centuries. He authored works on every one of those eras after a profound study founded upon two principal pillars: oral transmission and written sources. Such comprehensiveness was seldom achieved by the scholars who preceded him or even those who were his contemporaries.

When al-Dhahabī composed his Tadhkirat al-Ḥuffāẓ and arranged it by generations, he discussed
