This research aims to study the effects of emergency conditions on banking leasing contracts of its three types: operational leasing, leasing ending with ownership, and iron safes leasing. And an explanation of who is responsible for the loss of the leased property in the emergency situation, and who bears the harm of not fulfilling the benefit. I have followed the inductive approach in this research by collecting and extrapolating what was written about bank leasing from the books of contemporary scholars, and took the comparative approach, and mentioned the sayings of scholars and their evidence in issues of emergency circumstances, and the discussions they cited in these issues, with weighting as much as possible, and perhaps one of the most important The results of the research are that emergency circumstances may respond to the contract and dissolve it from its origin, such as the total destruction of the leased property, and the contract with it may remain as the destruction of the property described in the sukuk.
