Several features matter:
1. Qiṣāṣ (القصاص) specifies legally regulated retaliation rather than killing indiscriminately.
2. Ḥayāh (حياة) highlights preservation of life.
3. The principle addresses the affected family, potential offenders and society more broadly.
4. The brief structure avoids unnecessary repetition.
The lesson is not a competition in counting Arabic letters. Its concision is appreciated through the precision, scope and persuasive force of the meaning.
