وَلَكُمْ فِي الْقِصَاصِ حَيَاةٌ
And in lawful retaliation there is life for you.
Retaliation and life may initially seem an unexpected pairing. The deterrent and protective function of a regulated legal response supplies the link. A compact formulation produces surprise and then intelligible reconciliation.
It would be imprecise to label every surprising juxtaposition as ṭibāq. Qiṣāṣ and ḥayāh are not straightforward lexical antonyms; concision and a contextually explained relation are more secure observations.
