Slavery in Islam

Why the “Trajectory of Manumission” Argument Fails

Slavery represents one of humanity’s darkest and most enduring moral failures. Yet in the discourse around Islam, apologetics often attempt to portray the religion as progressive, emphasizing a so-called “trajectory of manumission” that allegedly nudges society toward eventual abolition. This argument claims that the Qur’an and Hadith advocate kindness to slaves and encourage eventual freedom, suggesting that Islam laid the groundwork for the moral improvement of society over time. However, a detailed analysis of the historical, textual, and ethical realities of slavery in Islamic societies reveals that this narrative is deeply flawed and misleading.

The Apologetic Narrative: Manumission vs. Abolition

Modern defenders of Islam frequently claim that the Prophet Muhammad was revolutionary in his approach to slavery, that his teachings encouraged humane treatment and laid the moral groundwork for eventual liberation. They argue that the Qur’an instructs believers to treat slaves with compassion and rewards acts of manumission. Yet, this narrative ignores the critical fact that Islam regulates slavery without condemning it. Optional acts of kindness and manumission do not constitute an abolitionist ethic; they are merely charitable recommendations that left the institution legally intact.

The Qur’an and Hadith include numerous references to slavery, consistently outlining rules for treatment but never challenging the institution itself. Commands to free slaves are framed as meritorious actions rather than obligatory reforms. As a result, slavery persisted for centuries in Islamic societies, with legal and social structures supporting its continuation. These historical realities directly contradict the apologetic narrative of gradual moral progress.

Textual Reality: Qur’an and Hadith on Slavery

Slavery is mentioned over forty times in the Qur’an, primarily in the context of regulating the institution rather than abolishing it. Verses encourage humane treatment, recommend acts of manumission as virtuous, and provide guidelines for sexual relations with female slaves. However, none of these passages establish an ethical imperative to dismantle the system. For instance, Surah An-Nisa (4:36) encourages kindness to slaves, but this is presented as a recommendation for pious conduct rather than an enforceable mandate to liberate them.

The Hadiths mirror this pattern. Prophetic traditions emphasize fair treatment and occasionally encourage freeing slaves, yet they never condemn concubinage or the ownership of human beings. Generational slavery was common: children born to enslaved women often inherited their mother’s status, embedding bondage across generations. These texts demonstrate that the so-called trajectory of liberation was theoretical and optional, rather than a binding moral or legal principle.

The Flaw in the “Trajectory” Argument

Apologists frequently argue that Islam’s approach to slavery represents a moral trajectory toward liberation, suggesting gradual reform was necessary due to social constraints. This argument fails on several counts. First, it ignores the lived experiences of countless individuals who endured slavery for generations. Gradual reform does not mitigate the moral consequences of systemic oppression. Second, the historical persistence of slavery in Islamic societies undermines the notion that the Qur’an or Hadith actively promoted abolition. The “trajectory” is a theoretical construct rather than an operational principle.

Historical Persistence of Slavery in Muslim Societies

Slavery was not an abstract issue in early Islamic societies; it was deeply embedded in economic, legal, and social structures. Across Africa, the Middle East, and the Indian Ocean, slavery persisted for centuries, sanctioned by Islamic law. In Mauritania, Sudan, the Ottoman Empire, and along Indian Ocean trade routes, enslaved individuals worked under legal and social conditions that institutionalized their bondage. Islamic law regulated inheritance, concubinage, and the status of children of enslaved women, ensuring the persistence of slavery. Even where manumission occurred, it was often selective, motivated by reputation or religious reward rather than justice.

Comparisons with non-Muslim societies further challenge the “trajectory” argument. European abolitionist movements, particularly in the 18th and 19th centuries, pursued liberation proactively, often under moral and political pressure. By contrast, Islamic legal systems provided no intrinsic incentive to dismantle slavery. The framework of Qur’anic law and prophetic tradition accommodated and sustained human bondage, demonstrating that Islamic ethics permitted rather than opposed the practice.

Manumission as Tokenism

Encouragement of manumission existed within Islamic texts, but enforcement was inconsistent and largely symbolic. Masters could choose to free slaves for moral merit, social reputation, or personal piety, but they were under no moral or legal obligation to do so. This tokenism perpetuated systemic inequality, as freed slaves were often isolated or dependent on the goodwill of former masters. Historical examples of slave markets in the Ottoman Empire and the Arab world illustrate that the structural and economic foundations of slavery remained intact, despite religious exhortations for occasional acts of liberation.

The Qur’an and Hadith establish a moral reward for freeing slaves, yet they do not challenge the ethical legitimacy of ownership. This reflects a broader principle within Islamic law: regulation without abolition. Acts of kindness are encouraged, but systemic injustice is left unaddressed. As a result, manumission functions as a palliative rather than a path to justice.

The Moral Failure of Apologetics

Apologists frequently invoke historical context, arguing that Muhammad’s approach to slavery was progressive for his era. However, contextualism cannot erase the reality of oppression. Ethical evaluation must consider the rights and dignity of enslaved individuals rather than the relative norms of historical societies. Figures such as Abu Ala Mawdudi explicitly defended slavery within Islamic jurisprudence, highlighting that entrenched traditions of ownership were regarded as morally acceptable. This underscores the inadequacy of contextual arguments: systemic injustice persisted for centuries under the sanction of religious law.

The Global Abolitionist Movement and Muslim Participation

When slavery was challenged, change often came from outside traditional Islamic structures. African and Middle Eastern abolitionist movements, as well as ex-slave advocates, pushed against entrenched religious and social norms. Even when Muslims contributed to abolition, their efforts frequently contradicted prevailing Islamic jurisprudence rather than emerging organically from scripture. This demonstrates that the “trajectory of manumission” is largely theoretical; reform occurred primarily through external pressures rather than internal moral evolution.

Modern Muslims Reject Slavery—But Why?

Today, slavery is overwhelmingly rejected across the Muslim world. Yet, this transformation owes more to global human rights movements, international law, and ethical development than to intrinsic religious mandate. Modern Islamic scholarship often condemns slavery, but historical textual and legal frameworks offer no compelling moral imperative for abolition. Contemporary rejection of slavery thus reflects societal and ethical progress, not the fulfillment of inherent scriptural principles.

Slavery as a Case Study in Islamic Moral Limits

Examining slavery reveals the limitations of Islamic moral innovation. Muhammad’s reforms improved conditions for slaves, promoting humane treatment and occasional manumission, yet the institution itself remained intact. Apologists frequently cherry-pick these reforms to portray Islam as morally progressive while ignoring the broader system of structural inequality and generational bondage. The persistence of slavery for centuries indicates that textual regulation reinforced, rather than mitigated, systemic oppression.

Ethical Implications and Modern Reflection

Understanding the reality of slavery in Islamic societies is critical for evaluating claims of inherent moral progress. While acts of manumission and kindness are documented, the structural and systemic aspects of slavery remained sanctioned. Modern ethical evaluation must confront the historical and textual realities rather than rely on apologetic reinterpretations. Islam’s engagement with slavery illustrates the limits of incremental reform and the dangers of relying on optional acts of virtue in place of fundamental moral imperatives.

Conclusion

The “trajectory of manumission” argument collapses under scrutiny. Islamic texts regulate but do not abolish slavery; Hadiths reinforce structural inequality, and historical evidence demonstrates centuries of persistent bondage. Contemporary Muslim rejection of slavery reflects external ethical evolution rather than fulfillment of scriptural morality. Honest engagement with these realities is essential to critically understanding Islam’s historical and moral relationship with slavery. Only by acknowledging uncomfortable truths can we assess the limits and implications of religious ethics in the context of human rights.
