The two Islamic partnership contracts behind halal business funding, investment accounts and startup deals

Reviewed quarterly and updated for major content changes.
Mudarabah is a one-way partnership: an investor funds a manager who runs the business, profit is shared by ratio, and the investor alone absorbs losses. Musharakah is a two-way partnership where every partner puts in capital and losses are shared in proportion to capital. Choose Mudarabah when you have capital but not time or skill (or when you have skill but no capital); choose Musharakah when both sides are investing money and want shared control. Islamic banks use Mudarabah for profit-sharing deposit accounts and Musharakah for financing where the customer brings equity.

Capital from one side, work from the other
One party (rabb al-mal) provides all the capital and the other (mudarib) provides the labor and management. Profit is split by a pre-agreed ratio; financial loss falls entirely on the capital provider unless the manager was negligent or breached the agreement. Governed by AAOIFI Shariah Standard 13.
Both sides put in capital
Two or more partners contribute capital (and usually work) to a venture. Profit is shared by an agreed ratio; losses are shared strictly in proportion to capital contributed. Governed by AAOIFI Shariah Standard 12. Diminishing Musharakah is the variant used in home financing.

| Dimension | Mudarabah | Musharakah |
|---|---|---|
| Who contributes capital | Only the investor (rabb al-mal) | All partners |
| Who manages | Only the mudarib; investor cannot interfere in day-to-day management | Any or all partners, as agreed |
| Profit split | Any ratio agreed in advance (e.g. 70/30) | Any ratio agreed in advance; a sleeping partner's share cannot exceed their capital share under Hanafi and Hanbali views |
| Loss split | 100% to the investor; mudarib loses only their effort | Strictly by capital share, no exceptions |
| Manager liability | Liable only for negligence, misconduct or breach of terms | Each partner liable for their own negligence; agents of one another otherwise |
| Capital guarantee allowed | No. A guaranteed return of capital turns it into a loan | No. A partner may not guarantee another's capital |
| Where you meet it | Islamic bank savings and investment accounts, fund management, angel investment in a founder | Joint ventures, project finance, halal home financing (diminishing form), business lines |
| Exit | Either party may terminate on notice; assets are liquidated or valued and profit settled | Partner sells their share to the others or a third party, or the venture is wound up |
If…
You have savings and a friend has a business idea and the skills to run it
Choose Mudarabah
You supply capital, they supply work. Agree the profit ratio in writing. Understand that if the venture loses money honestly, the loss is yours.
If…
Two or three people are each putting cash into a new company
Choose Musharakah
Everyone has capital at risk, so losses can be shared fairly by contribution and all partners can take part in management.
If…
You are choosing an Islamic bank account and want returns rather than a fixed rate
Choose Mudarabah (profit-sharing investment account)
The bank is the mudarib investing your deposit; you receive a declared share of the pool's profit, not a promised rate.
If…
You want to finance equipment or property with a halal provider while keeping equity
Choose Diminishing Musharakah
You and the financier co-own the asset and you buy out their share over time, paying rent on what they still own.
No. A fixed or minimum return to the capital provider is riba, because it is a guaranteed payment on money regardless of outcome. What the parties can do is agree a profit ratio and set a target the manager aims for; they can also agree that profit above a hurdle goes to the manager as an incentive. The capital itself cannot be guaranteed by the mudarib, though a third party unconnected to the deal may volunteer a guarantee.
Because the manager has already lost something real: their time and work, for which they receive nothing if there is no profit. The structure deliberately matches each party's loss to what they contributed. If the manager was negligent or broke the agreement, they become liable for the loss.
They are the closest conventional analogues. A limited partnership with a passive capital partner and an active general partner resembles Mudarabah; a member-managed LLC with capital from everyone resembles Musharakah. The Shariah requirements sit on top of the legal form: no guaranteed returns, losses by capital share, profit by agreed ratio, and a halal business. You can write these terms into an operating agreement.
Mudarabah. In a profit-sharing investment account the depositor is the capital provider and the bank is the manager, investing the pooled funds in halal financings and paying a declared share of the profit. This is why returns are announced after the fact rather than promised in advance.
Scholars differ. The majority view is that a partner cannot draw a fixed salary for managing the partnership because that would be a guaranteed return; instead the working partner is given a larger profit share. Some contemporary boards permit a market-rate management fee under a separate agency (wakalah) contract if all partners agree. Follow the ruling of the Shariah board or scholar you rely on.
