Addendum to the Share & the Shoemaker: The Mudarabah Precedent, Ottoman Codification, and the Consistency of the CRI Framework

Since the publication of "The Share, the Shoemaker, and the Structure of Zakat," several responses have pressed the argument that publicly traded shares should be assessed for zakat at their full market value. The objections merit further development on four points that the original article did not address at length: the classical precedent of the silent partner, the Ottoman treatment of shares and capital, the internal coherence of the CRI framework across corporate and individual levels, and the state of the classical evidence on productive asset exemption.

1. The Mudarabah Precedent

The strongest classical precedent for how the tradition treats a passive investor’s zakat obligation is the mudarabah. In a mudarabah arrangement, the capital provider (rabb al-mal) delivers funds to the working partner (mudarib), who invests, trades, and manages the capital according to the terms of the contract. The rabb al-mal cannot walk into the warehouse and take inventory. He cannot direct specific transactions. He has no operational control over the day-to-day disposition of partnership assets. His access to his own capital is restricted by the terms of the contract, and his share of the profit is contingent on the mudarib’s performance.

This is, structurally, the same position that a passive shareholder occupies in a modern corporation. The shareholder delivers capital. Management deploys it. The shareholder cannot direct specific corporate transactions, access the company’s inventory, or dispose of corporate cash.

Yet no legal school has ever assessed the rabb al-mal’s zakat obligation on the speculative or market value of his participation right. The tradition assesses him on his proportional share of the partnership’s zakatable wealth: its cash, receivables, and trade goods. The productive assets that generate returns are excluded from the assessment.

The question is not "can the rabb al-mal physically hand over inventory to the poor?" He cannot, whether we use market value or CRI. The question is: "What does he own that has value, and how does the tradition categorize that value for zakat purposes?" The tradition’s answer, across the schools, is that he owns a proportional interest in the partnership’s zakatable wealth, and that the productive capital generating the returns is categorically exempt.

The CRI methodology applies this principle to the corporate form. If it is sound for the mudarabah, it is sound for the publicly traded corporation. No one has identified a classical basis for distinguishing between the two.

2. What Senturk Actually Wrote

Omer Faruk Senturk’s Charity in Islam has been cited in support of the view that shares should be assessed at full market value. A closer reading of the text shows the opposite.

Senturk writes of "fabrikanin icindeki emtianin karsiligi olan senetlerdeki durum," meaning "shares that represent the goods (emtia) inside the factory." The term emtia, cognate with the Arabic amti’a, refers specifically to trade goods and inventory, not to abstract market rights or voting claims. Senturk is describing the classical distinction between a company’s capital assets (its buildings, machinery, and productive infrastructure) and its current assets (its goods, cash, and receivables held as property and wealth).

This is precisely the distinction that the CRI methodology preserves: productive capital is exempt; current assets are zakatable. Those who cite Senturk in favor of full market-value assessment have misread him.

3. The Corporate-Shareholder Consistency Principle

Some have argued that the CRI methodology would be appropriate if applied at the corporate level but that shareholders should pay zakat on the market value of their shares. This position contains a fatal contradiction.

If CRI correctly identifies the zakatable components of a business enterprise, distinguishing current assets (cash, receivables, inventory) from exempt productive capital (equipment, buildings, intellectual property), then that categorization does not change based on who is paying. The zakatable character of wealth is determined by its nature, not by whether the obligation is discharged by a corporation acting on behalf of shareholders or by shareholders calculating their own obligation.

Consider the implication. If a corporation were to pay zakat on behalf of its shareholders, it would correctly exclude its productive assets and assess only its current assets. But if that same corporation does not pay zakat, and the shareholders must calculate their own obligation, then on the market-value view, the productive assets that were correctly excluded at the corporate level suddenly become included via the share price. The same machinery, the same factory, the same patents would be exempt in one scenario and taxed in the other.

This is not a coherent legal framework. Zakat tracks the nature of the underlying wealth, not the identity of the payer.

4. Classical Sources on the Productive Asset Exemption

The exemption of productive assets from zakat is not the position of one scholar, one school, or one era. It is the operating framework across the madhahib.

Al-Sarakhsi states the Hanafi rule directly: "There is no zakat on the trader’s tools… because nisab is al-mal al-nami (growth-generating wealth)." [al-Mabsut, 2/198]

Al-Majlisi records the same principle in the Shafi’i tradition: "The weaver’s tools, the camels that carry goods, the cattle for plowing are not assessed." [Lawami’ al-Durar, 3/435]

Al-Dasuqi articulates the Maliki rule for partnership wealth: "No zakat on a partner until his share reaches nisab." [Hashiyat al-Dasuqi, 1/480] The partner’s obligation is assessed on his proportional share of the partnership’s zakatable wealth, not on the total market value of his participation interest.

These are not peripheral citations. They represent the operative consensus of the tradition. The market-value position, by contrast, has not produced a single classical source imposing zakat on productive assets or establishing that publicly traded shares should be assessed differently from private partnership interests.

If someone wishes to pay more than the tradition requires, assessing their shares at full market value as a precaution, that is their prerogative, and it may reflect commendable generosity. But to mandate market-value assessment as the position of the Deen, and to characterize the CRI methodology as a stratagem for reducing one’s obligation, is a claim that the classical sources do not support.
