Musharakah is a joint partnership in Islamic finance where all parties contribute capital and share in both the profits and losses of the venture according to their respective investment ratios. Unlike Mudarabah, where only one party provides capital, Musharakah involves shared financial contribution and shared risk.
Profits in a Musharakah may be distributed according to a pre-agreed ratio that can differ from the capital contribution ratio (reflecting different levels of effort and expertise). However, losses must be shared strictly in proportion to each partner's capital contribution — a partner cannot bear a higher percentage of loss than their capital share.
Musharakah has significant applications in modern Islamic banking, including diminishing Musharakah for home financing. In this structure, the bank and the customer jointly purchase a property. The customer gradually buys out the bank's share through periodic payments, and the bank's ownership share diminishes over time until the customer owns the property entirely. This provides a Shariah-compliant alternative to conventional mortgages.
