How incidental interest income is removed, why capital gains raise a further question, and how managers may be paid Read the bilingual lesson for Equity Funds: Purification and Fund Management and test your understanding with a focused quiz.
Lesson
1. What Is Purification?
When an otherwise acceptable company earns a small portion of income from interest-bearing deposits or similar sources, that impermissible portion should not be kept by the shareholder.
In an equity fund, removing that proportion from the investor’s benefit and giving it to charity is commonly called purification. The purpose is not to earn reward from prohibited income, but to remove it from personal benefit.
2. A Simple Dividend Example
Suppose 5% of a company’s total income came from interest-bearing deposits. If an investor receives a dividend, the same 5% proportion of that dividend should be removed and given to charity under the purification approach described.
The calculation follows the prohibited-income ratio rather than an arbitrary amount.
3. Do Capital Gains Also Need Purification?
Scholars differ on this question. One view says yes, because the market value of a share may partly reflect the company’s total assets and income, including a small impermissible element.
Another view says purification is not required on capital gain because no identifiable portion of the sale price can be specifically assigned to the company’s interest income.
4. Why the More Cautious View Purifies Capital Gains Too
The more cautious approach prefers purification of both dividends and capital gains. One reason is consistency: all unit-holders are treated similarly whether they exit the fund before or after dividends are received.
Without this, one investor might redeem before a dividend purification reduces the fund value, while another redeems later and indirectly bears a larger purification effect.
5. How Capital-Gain Purification May Be Estimated
Because the exact impermissible element inside market appreciation cannot usually be identified transaction by transaction, an average percentage may be used based on the interest income of companies held in the portfolio.
This is an approximation designed to apply the purification principle consistently across the fund.
6. Management Method 1: Mudarib (مضارب)
Fund managers may act as managing partners (مضارب) for subscribers. In that case, management receives an agreed percentage of actual profit.
If the fund earns no profit, the manager does not earn that profit share. As fund profit increases, the manager’s agreed share also increases.
7. Management Method 2: Agent (وكيل)
Alternatively, management may act as an agent (وكيل) for investors. In that case, it can receive a pre-agreed fee for services.
The fee may be a lump sum, monthly or annual amount, and the contemporary view described also allows a fee based on a percentage of the fund’s net asset value (NAV).
8. Why the Management Method Must Be Chosen Before Launch
The fund should clearly choose its management model before launch. Investors need to know whether management will be rewarded through a profit share or through an agency fee.
The prospectus is the practical place to disclose this. By subscribing with knowledge of the prospectus, investors are treated as agreeing to the disclosed management arrangement.
9. Why These Two Models Should Not Be Confused
In the Mudarabah model, management compensation depends on actual profit. In the agency model, the fee is payment for service and can be known independently of profit.
These are different legal relationships, so the fund should not switch between them after the fact simply to guarantee management a desired return.
