Murabaha is an Islamic financing structure where a financial institution buys an asset requested by a client and then sells it to the client at an agreed upon profit margin. It involves two sale contracts - first where the bank purchases the asset, and second where the client purchases it from the bank on a deferred payment schedule. Murabaha is the most widely used Islamic financing tool as it resembles a loan while complying with Sharia prohibitions on interest. The document then provides examples of how to calculate the cost and profit amounts in Murabaha transactions.
