The study of Ibn Taymiyyah's ideas on haram and halal in Islam remains relevant for understanding Islamic jurisprudence, ethics, cultural identity and contemporary issues. The purpose of the paper is to analyze Ibn Taymiyyah's works and identify his most important concepts for the Muslim community. The methods of analyzing fatwas, written by Ibn Taymiyyah, and methods of interpreting and comparing the concepts of forbidden and permitted in Islam were used to achieve the purpose of the study. The main conclusion of the study is that Ibn Taymiyyah was known for his research in Islamic law, theology and morality. The figure had conservative views, and due to his own reformist ideas, he was repeatedly convicted. Despite this, he criticized traditional teachings about Islam and supported the need to reform some aspects of Islamic practice. Ibn Taymiyyah attached great importance to the examination of Prophet Muhammad's Quran and Sunnah to understand what is forbidden and allowed in various areas of Muslim life. He stressed the importance of a healthy diet, the need to follow Islamic principles in financial matters and the preservation of dignity and respectful behavior in all aspects of life.
