Surah 90:11–13
But he has not broken through the difficult pass. And what can make you know what is the difficult pass? It is the freeing of a slave.
The moral center of the Surah challenges mankind to overcome a spiritual barrier called "the difficult pass" (al-ʿaqabah), defining it explicitly as: "the freeing of a slave (fakku raqabah)."
The Pragmatic Regulatory Model: Apologists frequently cite this verse as an ultimate proof of Islam’s progressive, anti-slavery trajectory. However, to a secular legal historian or human rights philosopher, this verse exposes a deeply flawed, conservative approach to institutional human trafficking.
The Structural Reality: The text treats the existence of human slavery (raqabah—literally meaning "a neck" under bondage) as a permanent, baseline feature of human civilization. The freeing of a slave is framed merely as a transactional, individual charity project designed to wipe away a wealthy Muslim’s personal sins, much like feeding an orphan in a time of famine (v. 14–15).
The Critical Conclusion: The Quran never takes the logical, moral leap of declaring the institution of slavery to be an inherent, capital crime against humanity. It never commands an absolute, immediate ban on owning, buying, selling, or sexually exploiting human captives (Ma Malakat Aymānukum).
By reducing emancipation to a voluntary, premium good deed used to scale "the difficult pass," the text effectively normalized and preserved the economic infrastructure of human bondage for over a thousand years across the Islamic world.
