Islamic Home Financing: A Complete Guide to Diminishing Musharakah


Owning a home is everyone’s dream. But with today’s prices, buying a house outright has become almost impossible for a salaried person. Around the world, the usual solution is a “mortgage”, a long term interest based loan for a home. For a Muslim, this path is closed, because the Quran describes interest as a war against Allah and His Messenger (Surah Al Baqarah 2:279).


Islamic banking offers an alternative called “diminishing musharakah”: a partnership in which you buy a house together with the bank, and gradually become the owner of the whole house. This guide explains this method with all its details, conditions and objections.


What Is Diminishing Musharakah?


Diminishing musharakah literally means “a diminishing partnership”. In practice, it is a partnership in which one partner’s share, the bank’s, gradually decreases, while the other partner, you, buys it bit by bit, until you own the whole asset.

This product is made up of three separate Shariah contracts:




  1. Shirkat al Milk (co-ownership): joint ownership of the house, like a house inherited by two brothers.
  2. Ijarah (lease): the bank leasing its share to you.
  3. Bai (sale): the bank selling its share to you in stages.


The Shariah Basis


Partnership is a permissible transaction established by the Quran, Sunnah and consensus. The Quran says about partners: "وَإِنَّ كَثِيرًا مِّنَ الْخُلَطَاءِ لَيَبْغِي بَعْضُهُمْ عَلَىٰ بَعْضٍ إِلَّا الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ" (Surah Sad 38:24), and indeed many partners wrong one another, except those who believe and do righteous deeds. This verse shows both that partnership is permissible and that honesty in it is essential.

Leasing and sale are each valid contracts in their own right. The only legal question is how these three can be combined while remaining valid; the answer is given below under “Shariah conditions”.


Understanding It Through an Example

Suppose you want to buy a house worth 10,000,000 rupees, and you have 2,000,000 rupees.


Step 1: Joint purchase:

You contribute 2,000,000 and the bank 8,000,000, and together you buy the house. Now your share is 20 percent and the bank’s is 80 percent.


Step 2: Division into units:

The bank’s share is divided into small portions, called “units”, for example 80 units of 100,000 rupees each.


Step 3: Rent on the bank’s share:

You live in the whole house, but 80 percent of it belongs to the bank. So you pay monthly rent only on the bank’s share, not on your own.


Step 4: Buying units:

Along with the rent, you buy some of the bank’s units each month. Each unit purchase is a separate sale.


Step 5: Rent keeps decreasing:

As you buy units, the bank’s share shrinks, and the rent falls in the same proportion.


Step 6: Full ownership:

When you have bought all the bank’s units, the house is 100 percent yours, and the partnership ends.


Summary of the example:



The Shariah Conditions of Diminishing Musharakah


Condition 1: The three contracts must be separate


This is the most fundamental condition. AAOIFI Standard No. 12 states clearly that it is not permitted for one contract to be entered into as a condition for concluding the other. In other words, the partnership agreement cannot say, “If you take this house in partnership, you must also lease it and buy it”; each contract must be independent and complete on its own. azmilaw


Condition 2: The promise to buy must be unilateral


To buy the bank’s share, the customer gives a unilateral promise (wa’d). The State Bank of Pakistan has also adopted AAOIFI Standard No. 49 on unilateral and bilateral promises, which refers to the binding nature of the institution’s promise in diminishing musharakah.

Condition 3: Pricing the units (a crucial issue)


This is the most sensitive issue in diminishing musharakah: how is the price of the bank’s share, its units, decided?

AAOIFI’s position: Under clause 5/7 of AAOIFI Standard No. 12, one partner may give a binding promise allowing the other partner to acquire his equity share gradually through sale, at the market value or a price agreed at the time of acquisition; however, it is not permitted to stipulate that the share be acquired at its original or face value, as this would amount to one partner guaranteeing the value of the other partner’s (the institution’s) share. islamicfinanceguru


The International Islamic Fiqh Academy’s position: The Academy’s resolution says the same: the pledge should not be to purchase the other party’s shares at par value, because the pledge would then amount to a guarantee; the purchase price of the shares should be determined at market value or a mutually agreed price.

What is the wisdom behind this? The spirit of partnership is that every partner shares in both profit and loss. If the house falls in value and the customer is still bound to buy the bank’s share at its original price, the bank’s capital is protected in every case; that is not partnership, but a loan like guarantee.


The situation in Pakistan: In Pakistan, diminishing musharakah is governed by the State Bank’s own separate standard. According to the State Bank, a self-contained Shariah Standard on “Sharikat ul Milk and Diminishing Musharakah” was notified through IBD Circular No. 2 of 2013. Islamic banks in Pakistan operate under this standard. Before signing, customers should ask their bank clearly how the unit price will be set.

Condition 4: Rent only after possession


Rent can only begin once the house is fit to live in and handed over to you. Charging rent for a benefit you have not received is not permissible.


Condition 5: Risk according to ownership


The bank is a co-owner of the house, so it bears the house’s risk in proportion to its share. This is what separates the arrangement from a loan.


Responsibility for Costs




  • Ownership related costs: such as takaful for the building and major structural repairs; these are shared by the partners in proportion to their shares. In practice, the bank includes its share of these costs in the rent.
  • Usage related costs: such as electricity, gas, water and routine upkeep; these are the occupant’s, your, responsibility.


What If the House Is Damaged?


In a conventional mortgage: The house is yours; the bank is only a lender. If the house is destroyed in an earthquake, fire or flood, you still owe the entire loan and interest, unless insurance covers it.


In diminishing musharakah: The bank is also an owner. If the house is destroyed by a disaster without your negligence, the loss falls on both partners in proportion to their ownership; in practice, this is managed through takaful.


What If You Cannot Keep Paying?


If for some reason you cannot continue payments and the house must be sold:




  • In musharakah, the sale proceeds are divided in proportion to ownership.
  • If the house has gone up in value, your share of that increase comes to you; the bank is entitled only to its own share.
  • Any rent you owe is paid from your share, since it is a debt you owe.


Houses Under Construction


If the house is still being built, no rent can be charged, because something that does not yet exist has given you no benefit. For such cases, Islamic banks use other methods approved by the Shariah board, such as istisna or forward ijarah, where rent starts only after the house is completed and handed over.


How Is Rent Set? The Benchmark Issue


In diminishing musharakah, the rent on the bank’s share is usually set using a benchmark such as KIBOR, and may change each year or after a set period. The same principle applies as in ijarah: the method of changing the rent must be agreed in advance, and the rent for each period must be fixed at the start of that period. Using a benchmark to set rent does not make the arrangement interest based, because the bank owns a share of a real house and bears its risk. This objection is examined in detail in Part Four.


Late Payment and Early Settlement




  • Late payment: The bank may not take extra money for itself; under your undertaking, a sum goes to the charity fund as charity.
  • Early full ownership: You can buy all the bank’s remaining units at any time and become the full owner. The rent then ends, because the bank no longer owns any share.


Conventional Mortgage vs Diminishing Musharakah




Common Objections and Answers


Objection 1: “Combining three contracts in one deal violates the ban on ‘two sales in one’.”


Answer: This is the oldest objection to diminishing musharakah, and various fatwa bodies have discussed it. The objection normally raised against diminishing musharakah contracts is that they combine two transactions into one, which is not allowed in Shariah. The answer is that the prohibition applies when one contract is made a condition of another. If the three contracts are separate, independent and complete with their own conditions, and the transfer of ownership rests only on a unilateral promise, this prohibition does not apply. AAOIFI and the International Islamic Fiqh Academy have permitted diminishing musharakah on this condition.

Objection 2: “The monthly payment is the same as a conventional mortgage.”


Answer: Equal payments do not make two transactions the same in reality. The real difference lies in ownership, risk, how losses are shared, and who benefits when the value rises, as the comparison above shows.


Objection 3: “The bank bears no real risk; everything is protected by takaful and guarantees.”


Answer: Managing risk is the right of every sensible trader; it does not deny that the risk exists. If takaful does not cover a claim, or the house falls in value, the bank bears the loss on its share. However, this objection becomes strong when the unit price is fixed in advance at original cost; that is exactly why AAOIFI and the International Islamic Fiqh Academy prohibit it.


Mufti Taqi Usmani’s View


In his book “An Introduction to Islamic Finance”, Mufti Muhammad Taqi Usmani describes diminishing musharakah as a better Shariah alternative for home financing, stressing that partnership, lease and sale must remain separate transactions and must not be made conditions of one another. In his view, compared to murabaha, this method is closer to the true spirit of Islamic banking: genuine partnership.

A Final Word


Diminishing musharakah is among the Islamic banking products furthest from interest in spirit, because the bank is a genuine partner and owner, not merely a lender. But its integrity depends on three things: the contracts must be separate, risk must follow ownership, and the unit price must be set so that the bank’s capital is not guaranteed in every case. For a Muslim who wants to achieve the dream of a home in a halal way, it is a practical path, as long as he understands his agreement before signing it.
