According to search-discovered classical Islamic scholarship, Quran 8:67, 'It is not for a prophet to have captives [of war] until he inflicts a massacre [upon Allah's enemies] in the land,' serves as a foundational principle in the Islamic ethics of warfare. Revealed after the Battle of Badr, this verse, as explained by tafsir scholars like Ibn Kathir and Al-Qurtubi, was a divine directive prioritizing the decisive weakening of the enemy's military strength over the taking of captives for ransom. [3, 22] The term 'yuthkhina' is understood not as a command for indiscriminate killing, but for a decisive engagement that secures the Muslim community. This verse establishes that enslavement is only permissible in the context of a legitimate war, as a means of dealing with captives when other options are not viable. It underscores a strategic and ethical framework where the ultimate goal is the establishment of peace and justice, not the acquisition of slaves or spoils. This principle is further elaborated in other parts of the Quran, which encourage the freeing of slaves and outline humane treatment for all captives. [1, 7]
