The advancement of Islamic countries and the emergence of new financial and economic development needs, as well as avoiding usury in the past two decades, have prompted Muslim scholars and thinkers to design Islamic finance instruments and replace them with new financial instruments. During this time, a number of Islamic finance instruments were designed and implemented. Financial managers and experts were confused about choosing the best-fitting tools for financing. Sukuk, as one of the most sophisticated Islamic finance instruments, has been able to put the right place between the government and the Islamic company. To this end, in this research, we tried to identify and prioritize the use of Islamic financial instruments, based on the risks, the scope and applicability of liquidity in the capital market by using Fuzzy Vicor Method. Due to the nature of uncertainty and ambiguity in the evaluation, fuzzy logic capabilities were used to complete the performance decision matrix. Finally, it was determined that the priority of financing through Islamic securities is, respectively, Treasury bills, Intangible Bonds, Leasing Bonds and Indebted Bonds.
