The present research aims to examine the conditions of countervalues in lease from jurisprudential and legal perspectives. The research method is descriptive-analytical using library sources. From the viewpoint of Islamic jurists, the two goods exchanged in a sale contract must possess certain characteristics. These characteristics include being tangible, having value, ownership, being unrestricted, ability to deliver, and being known. Studies have shown that the leased property, like the sold item, must be known. The first condition of countervalues is that each of them must be known. However, there is disagreement among jurists regarding the method of making the rent known. According to Sheikh Tusi's opinion, observation is sufficient in making the rent known, and its amount doesn't need to be specified. One of the conditions of the leased property is that it must be permissible to use. Therefore, hiring a mute person for teaching or hiring a menstruating woman to clean a mosque is not permissible. The leased item can be tangible, and this tangible item can be objects, animals, or humans, and it should have the ability to remain. The leased item should be something that can be utilized while its essence remains intact.
