Islamic scholars in the archipelago, especially Malaysia, Indonesia, and Southern Thailand have been active in producing works in various fields of Islamic studies. These areas such as fiqah, akidah, tasawuf, hadith and tafsir al-Quran. One of the works written in the field of interpretation of the Quran is Tafsir Nur al-Ihsan produced by Syeikh Muhammad Sa'id Umar. This work in the field of Quranic interpretation is a reading material as well as a reference to the public in understanding the contents of the Quran. However, the background and background of Syeikh Muhammad Sa'id Umar was not fully disclosed by the previous researchers. Only a small part of his background was discussed. The community only studies and references Tafsir Nur al-Ihsan without knowing the author of the work. Therefore, this study was carried out to study and reveal the background of Sheikh Muhammad Sa'id Umar covering birth, study, and contribution until his death. In conducting this research, researchers apply the method of historiography studies and library studies to analyze and expose the matter. It is hoped that after the study is completed, it will provide new knowledge to the community about Syeikh Muhammad Sa'id Umar, author of Tafsir Nur al-Ihsan.
