The ability of sukuk types, which play an important role in the liquidity management of interest-free financial institutions, to be traded in the secondary market is of vital importance for these institutions. In order for sukuk certificates to be traded in secondary markets, the sukuk must be issued as asset-based, not debt-based. The Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI) has published a standard on sukuk, and a clear understanding of this standard is very important for interest-free financial institutions that issue sukuk and use it in liquidity management. This is because these financial institutions should not trade some sukuk certificates in the secondary market and use them in liquidity management, as the sale of debt is prohibited by law. The purpose of this article is to investigate the types of sukuk issued by the state institutions of various countries and to determine whether these sukuk types are suitable for trading in the secondary market according to the AAOIFI sukuk standard and the prohibition of debt sale (bay'al-dayn). In the article, it was determined that some of these sukuk types were introduced to the market for liquidity management purposes even though they are not suitable for the secondary market in terms of fiqh.
