Penetapan Harga Menurut Yahya Bin Umar dan Relevansinya Terhadap Undang-Undang Penetapan Harga Di Indonesia[Pricing According to Yahya Bin Umar and its Relevance to the Law on Pricing in Indonesia]

The most perfect religion is Islam because it regulates all aspects of life, both in terms of worship and muamalat. Halal buying and selling based on the principle of mutual pleasure in accordance with the provisions of the Shari'a in order to achieve a sense of justice has been ordered in Islam. The method used in this research is qualitative by utilizing the legal perspective approach of Islamic Economics. From the results of the study: it was concluded that 1) Yahya bin Umar's thoughts forbade the government to intervene in determining prices. 2) Currently, the Indonesian government's economic policy is not yet ready to determine prices without government intervention, so that the government still needs its intervention in determining prices. 3) the relevance of the price may be intervened by the government in abnormal conditions. From this research, it is very important for the Indonesian government to implement Islamic sharia patterns in intervening in determining prices for the sake of achieving the common good and the welfare of the people.
