According to search-discovered classical Islamic scholarship, the freeing of slaves, known in the Quran as 'Tahrir al-Riqab' (liberating necks) and 'Fakk Raqabah' (freeing a neck), is a foundational act of piety and a key component of Islamic social justice. Tafsir authorities like Ibn Kathir and Al-Qurtubi explain that the Quran did not simply condone manumission but actively institutionalized it through a multi-faceted system. This divine framework established freeing a slave as one of the highest forms of righteousness (2:177), a difficult but virtuous deed on the 'steep path' to God (90:13), a mandatory legal expiation (Kaffarah) for specific sins such as accidental killing (4:92) and broken oaths (5:89), and one of the eight official categories for the distribution of Zakat (9:60). Furthermore, the Quran introduced the 'mukataba' (24:33), a contractual path for slaves to purchase their own freedom. This comprehensive synthesis across multiple Quranic contexts reveals a clear divine trajectory aimed at systematically dismantling the pre-existing institution of slavery by creating numerous, spiritually potent incentives for emancipation.
