The subject of the article is related to the compliance of UCP 600 rules with participation banking, which is one of the problems specific to participation banking (Islamic banking) in the form of letters of credit. Participation banks, similar to traditional (conventional) banks, issue letters of credit on behalf of importers and in favor of exporters in international trade transactions, or act as a advising bank or confirmation bank in a letter of credit. A Sample Procedures and Application Rules booklet on Letters of Credit prepared by the International Chamber of Commerce (ICC) was published in 2007 under the name UCP 600. UCP 600 is a set of rules prepared without envisaging a deciency between traditional banking and participation banking. Since these rules are generally accepted by all banks worldwide, they are strictly applied by both traditional banks and participation banks today. However, some of the articles of this directory of rules are not rules that comply with Islamic financial standards. Some researchers suggest preparing a different UCP document specific to Islamic banking by evaluating some of the articles of the UCP 600 in order for it to be applied in a fiqh-appropriate manner by participating banks. Some researchers have suggested that the following rules should be applied. Since these rules applied globally regarding letters of credit are not suitable for Islamic banks, an Islamic organization specific to this issue should be established. This organization should publish a separate standard for Islamic banks. The Islamic banking network should be expanded. Islamic letters of credit should be applied differently in practice. For this reason, while applying UCP 600, the fiqh rules should also be observed simultaneously. The ICC should publish a standard that can be used jointly for both traditional and Islamic banks. The purpose of writing the article is to analyze whether participation banks need a jurisprudence-compliant UCP 600 rules directory and to detail by finding the issues that participation banks should pay attention to in terms of jurisprudence in letter of credit applications. For this purpose, the qualitative research method based on literature review, comparison, evaluation and analysis was used in the article. First of all, the findings of the research conducted on the subject were summarized by conducting a literature review. Subsequently, in order to determine the compliance of the UCP 600 rules index with the AAOIFI Letter of Credit Standard published by the Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI) in 2003, some items of both documents were subjected to comparative evaluation. Subsequently, the results of the evaluation were analyzed and the findings were reached. Since the findings obtained in the article are to guide participation banking on which items of UCP 600 should be excluded from practice when applying with letter of credit paying methods, the study is important from this point of view, and a study similar to the analysis study conducted in the article was not found in the literature review. The reason for using the AAOIFI Letter of Credit Standard at the analysis stage is because the AAOIFI standards are generally accepted by Islamic banks worldwide and the standard prepared by AAOIFI is the most comprehensive standard published in the field of Islamic banking in relation to letters of credit. In the article, the articles of UCP 600 and AAOIFI Letter of Credit Standard, which are considered to be contradictory with each other, are analyzed mutually. As a result of the analysis, the following items are included in UCP 600; pays decrees, ”relationship of contracts between the parties with letter of credit“, ”relationship of goods and services with letter of credit“, ”interest payments“ and ”policy and documents negotiation" standards have been found to be incompatible for participation banks. It has been concluded that the preparation of a fiqh-compatible UCP rules index to eliminate these incompatibilities cannot fully solve the problems. We can summarize the findings reached as follows. Participation banks must continue to open letters of credit subject to the current UCP 600 rules. They should not open letters of credit based on contracts that are not compatible from a fiqh point of view, or they should not be a party to letters of credit opened in this way. They should take all measures to ensure the availability of the goods in the murabaha letters of credit they open. They should proceed to the operational stage after removing the articles of non-compliance with the law contained in UCP 600 from the text of the letter of credit and having them accepted by the other parties.
