What is the ruling when a one-eyed person intentionally injures the eye of a healthy, two-eyed person?
Chapter on Retaliation (Qawad)

Primary text
When a one-eyed man deliberately damages the eye of a healthy, two-eyed man, the injured party has the choice. He may choose retaliation (Qisas), in which case he takes the aggressor's single eye and nothing more. Alternatively, he may opt for monetary compensation (Diyah). If compensation is chosen, only a single Diyah is due because the Prophet (peace be upon him) stated, "For the two eyes, there is the Diyah." Furthermore, since full retaliation (Qisas) was not impossible, the Diyah is not doubled, similar to cases where an amputated hand damages a healthy hand, or if the aggressor's head was smaller, or if the aggressor's cutting hand was deficient. This view is held by the majority of scholars and aligns more closely with the textual evidence and sound legal reasoning.

The Qadi held that juristic principles suggest two full Diyah payments are due to the victim: one for the eye corresponding to the aggressor's lost eye, and a second Diyah because the injured party possessed a bulging eye (A'war - a defect mentioned implicitly in the context of the aggressor's status).
