This document discusses the principles of form over substance and substance over form in Islamic finance. It provides examples of how substance over form is applied in certain cases where form and substance are inconsistent, such as in Ijarah Muntahiah Bittamleek contracts and evaluating offer and acceptance. While form is important in ensuring legal and Sharia compliance, substance is also important to assess the true economic nature of a transaction. The Sharia Advisory Council has ruled that both substance and form should be consistent, but substance takes precedence over form in cases of inconsistency.
