This study seeks to compile and examine the jurisprudential issues transmitted by the reliable hadith scholar Ali bin Zakariya Al-Tammar from Imam Ahmad, tracing their presence across Hanbali legal texts, biographical and class literature, and works on Islamic etiquette. Employing both inductive and deductive methods, the research is structured into an introduction, a preface detailing Al-Tammar’s biography, and three chapters covering his narrations on worship, transactions, and A’adab (etiquette). The findings reveal that Al-Tammar conveyed only a limited number of issues—four in total—each encompassing several subtopics, some aligning with the Hanbali school and others diverging. These narrations differ in their documentation and attribution, appearing in biographical sources, jurisprudential writings, and Islamic A’adab texts.
