وَلَكُمْ فِي الْقِصَاصِ حَيَاةٌ
And for you there is preservation of life in lawful retaliation.
This clause from Al-Baqarah 2:179 is concise but carries a broad social rationale: a regulated law of retaliation protects life by restraining homicide. Its economy of wording with substantial relevant meaning is a classic case of iʿjāz al-qaṣr.
The wording does not endorse private vengeance or indiscriminate violence. Qiṣāṣ is a defined legal concept; collapsing it into revenge would misstate both the proposition and its rhetorical design.
