Abstract: Ibrahim Hosen was a prominent religious figure and Islamic legal thinker in Indonesia who focused intensely on the field of fiqh (Islamic jurisprudence). His ideas and thoughts aimed to assimilate national law with Islamic law so that the two legal systems would not contradict each other. However, some of his views were often considered controversial and deviated from the general understanding of mainstream ulama (Islamic scholars). Ibrahim Hosen applied a method of ijtihad (independent legal reasoning) that prioritized rationality in formulating Islamic legal rulings. The concept of Indonesian fiqh should ideally accommodate all interests in order to achieve just and equitable laws. Society should be given the freedom to choose their own madhhab (school of thought), while the government should adopt a neutral stance and embrace all groups to prevent religious discord.
