Asset management companies have emerged with the aim of purchasing the non-performing assets of financial institutions, providing liquidity to the institution and freeing these institutions from non-performing assets. The deterioration in the economies of countries from time to time and the consequent deterioration in the economic situation of citizens and financial institutions have led to the establishment of these companies. Although asset management companies emerged earlier in the world, they came to the agenda in our country after the 2001 crisis. Since asset management companies were established with the aim of purchasing non-performing assets from conventional banks at very low amounts and collecting these debts from the original owner, we cannot say that they take into account the prohibition of interest, which is not legitimate according to Islamic law. Therefore, it is not possible to state that the existing asset management companies are legitimate in terms of Islamic law. On the other hand, considering that participating banks may also have problematic assets, there should be a need for an Asset Management Company that conducts interest-free transactions and complies with the principles of Islamic law. In this context, it should be necessary to determine some principles for asset management companies that aim to operate within the framework of the principles of Islamic law. In the history of Islamic law, debt-sale practices have been widely discussed by scholars. The main source of the debate is the hadith narrated from the Prophet (p.b.u.h.), "The Prophet (p.b.u.h.) forbade the sale of debt for debt." As a matter of fact, many opinions have been expressed around this hadith, and it has been stated that the hadith is weak, and although it has been stated that it is weak, there are also opinions that it is true in terms of its meaning. On the other hand, there are also disagreements about which of the debt-selling practices the hadith covers. Some scholars accepted the hadith as absolute and did not allow any debt to be sold in any way. Some scholars, on the other hand, have narrowed the scope of the hadith and stated that it is not permissible to engage in debt-sale practices that create an interest transaction or where the transaction does not benefit people. The Hanafi madhhab has never authorised the sale of debt on the grounds that it is not deliverable. Although the Shafi'i madhab has such a view as a sect, it has experienced individual disagreements on the issue of purchasing the debt in cash in exchange for goods. The Maliki madhhab is more moderate than these two madhhabs in the practice of selling debt. As a matter of fact, it has adopted the view that it is possible to sell the debt to the debtor himself or to a third party in exchange for a good or benefit, with some conditions. The scholars who act most freely on this issue are Ibn Taymiyya and his student Ibn Qayyim al-Javziyye. According to these two scholars, the sale of debt forbidden by the aforementioned hadeeth is the sale of a new debt on a deferred basis without the parties having a previous debt in their possession. It is permissible to sell a debt that is fixed in the dhimma, either to the debtor himself or to a third party, in exchange for goods or the benefit of goods. In addition to the views mentioned above, among today's scholars or fatwa committees, some make ijtihad on the view of the Maliki madhab. For example, the Islamic Fiqh Academy and the Advisory Board of the Participation Banks Association of Turkey have expressed the opinion that practices that take place in the form of selling debt to third parties in cash in exchange for a property or the benefit of a property or a service may be permissible. In this article, since it is considered to be a current need, the issues of how an Asset Management Company can operate by the principles of participation finance should be and on the basis of which principles and with which methods it can purchase problematic assets are discussed. In this context, firstly, the practices in the classical fiqh works regarding debt sale practices are analysed and evaluated, and then an asset management company model that operates in accordance with Islamic law is proposed.
