As per Shariah requirements concerning financing, Manzil's relationship with the customer is a relation of a seller to a buyer (respectively) for Murabaha or a partner for Musharaka, and not a lender to a borrower as it is in conventional lending. It sounds semantic, but in fact, it is quite material.
A lender lends money and is repaid with more money (i.e., the interest, which is prohibited from a Shariah point of view). In contrast, Manzil finances the transaction through buy-and-sell activities (Murabaha) or a partnership (Musharaka). Therefore, there is a profit due to a transfer of ownership based on a real economic transaction and not interest (Riba), which is a fee paid to the lender for the privilege of using their money and solely based on the time going on and can grow unlimitedly as long as the balance is not paid back.
