This research was proposed by Siradjuddin Abbas who in some literature is not known as a hadith figure. He is better known as a prominent Indonesian theologian and fiqh expert. In fact, the thoughts and contributions of Siradjuddin Abbas in the study of hadith can be traced in his various works. This study aimed to reveal the contribution of Siradjuddin Abbas in the study of hadith. The descriptive-analytical method and the biographical approach were used to answer the questions: 1) whether Siradjuddin Abbas can be said to be a hadith figure, and 2) what is the contribution of Siradjuddin Abbas in the study of hadith in Indonesia. The results of the study indicated that; 1) Siradjuddin Abbas is not only a theologian and fuqahā’ but also a figure in Indonesian hadith. Although he did not write a specific hadith book, Siradjuddin Abbas’s thoughts on hadith are scattered in his various works. He was a collector, commentator and eristic of hadith in written and oral. 2) The roles and thoughts of Siradjuddin Abbas contributed to the study of hadith in Indonesia. He strengthens the argument for Ahlussunnah wal Jamā’ah’s understanding by providing hadith arguments on the thoughts of kalam and fiqh. Although the role, thought and understanding of the Hadith of Siradjuddin Abbas is more of a defence of the Asy’ariyah theology and the Shafi’i school, the thought of the hadith becomes a reference and guide for the Islamic community, especially from traditionalist Muslims
