Muhammad’s Economics is Wrong

The crisis of medieval war‑dependent economies: Prophet Muhammad’s economic model is inhumane and unacceptable

In medieval state systems — under the rule of Prophet Muhammad, the Byzantine, Roman, Mongol, or Islamic Caliphates — three sources of revenue were extremely common: war booty, the slave trade, and special taxes imposed on conquered populations. In light of modern economic theory, the structural weaknesses, inhumanity, and shortsighted policies of these models become clearly visible.

War-Booty-Based Revenue Model: Zero-Sum Economics

Theoretical Problem

The foundation of modern economics is Positive-Sum Growth — meaning that through production, innovation, and exchange, total wealth increases. But war booty (ghanimah) is a purely Zero-Sum transaction — one side loses and the other gains, and no new wealth is created.

Historical Comparison

The Ghaznavid case study is particularly relevant. Mahmud of Ghazni conducted 17 Indian campaigns. Each campaign was essentially plunder-driven. After his death, when the raids stopped, Ghazni quickly became a third-rate kingdom — because the state had never developed any productive economic structure of its own.

The Jizya Tax of the Islamic Caliphate: A Revenue Paradox

Structural Inconsistency

Jizya was a special tax imposed on non-Muslim citizens (dhimmis), in exchange for which they received protection and the right to practice their religion. But this model contained a fundamental Revenue Paradox:

Jizya revenue = Non-Muslim population × tax rate

But when conversions increase → non-Muslim population decreases → jizya revenue decreases

Meanwhile state expenditure → continues to rise

Historical Evidence: The Umayyad Crisis (718 CE)

During the rule of Umayyad Caliph Umar ibn Abd al-Aziz, mass conversions in Egypt and Iraq caused jizya revenue to drop dramatically. Local governors then began collecting taxes even from new Muslims — which was a direct violation of religious policy. This proves that economic realities repeatedly forced ideological structures to compromise.

The Mughal Dilemma

Akbar abolished jizya (1564) — because he understood that alienating India’s vast Hindu peasant and merchant classes would collapse revenue. Aurangzeb reinstated it (1679) — and the result was Maratha rebellion, Sikh resistance, and rapid imperial decline.

Slave-Based Economies: Structural Limits to Productivity

Economic Theory

Nobel laureate economist Douglass North, in his theory of Institutional Economics, showed that slavery never encourages technological innovation — because:

• If a slave’s productivity increases, the benefit goes to the slave, not the owner
• Thus owners have no incentive to invest in technology
• The quality of labor remains stagnant

The Zanj Rebellion (869–883 CE): A Case Study

The rebellion of African slaves (Zanj) in Abbasid Iraq lasted 14 years. This rebellion:

• Destroyed the city of Basra
• Completely collapsed the agricultural infrastructure of southern Iraq
• Caused financial losses to the Abbasid treasury that took decades to recover

This proves that a slave-dependent economy is not only morally wrong but also structurally unstable.

Zakat in the Islamic Economic Structure: A Different Assessment

One important point must be honestly acknowledged in this discussion. Alongside the three elements above, zakat was a tool of a completely different nature in the Islamic economic system.

The Structure of Zakat

Economic Logic of Zakat

From a modern perspective, zakat contains some effective redistribution principles:

• It activates idle capital (anti-hoarding)
• Transfers purchasing power to lower classes, creating demand
• Acts as a primitive form of social safety net

However, the limitations of zakat were also clear: it redistributed only among Muslims and did not create any structure for increasing production.

Comparative Picture: Which Model Survived?

History shows that the states which survived long-term moved away from war-based revenue and built productive structures:

The Abbasid Golden Age (8th–10th century) survived mainly because they:

• Adopted the Persian agricultural bureaucracy
• Made Baghdad a commercial hub
• Acquired technology through the translation movement

But whenever they became dependent on Turkish military slaves (ghilman) and war-booty income — decline became inevitable.

The Economic Model of Islam’s Prophet Muhammad Is Unrealistic

History is a ruthless examiner. Any medieval state — Islamic, European, or Asian — that depended on war booty, slavery, and discriminatory tax structures met the same fate.

The three essential conditions of a sustainable economy — free labor, technological innovation, and inclusive institutions — are not inventions of any ideology; they are economic truths proven by history.
