An ijarah contract whose underlying is an unidentified unit of asset that will be leased at a future date. It may also refer to a lease contract in which the lessor undertakes to provide a well-defined service or benefit without identifying any specific assets to render it. If a unit of the asset is destroyed or becomes defunct, the contract will not be terminated and the lessor provides a replacement.

This type of ijarah is also known as forward ijarah. It is also spelled “ijarah mawsufah fi zhimmah“.
