The arsh for causing itlaf of organs found in a human body in pairs shall be equivalent to the value of diyat and if itlaf is caused to one of such organs the amount of arsh shall be one-half of the diyat:
Provided that, where the victim has only one such organ or his other organ is missing or has already become incapacitated the arsh for causing itlaf of the existing or capable organ shall be equal to the value of diyat.
Explanation: Hands, feet, eyes, lips and breasts are included in the organs which are found in a human body in pairs.
Arsh for paired organs (hands, feet, eyes, lips, breasts) is full diyat for both, half diyat for one. If only one exists, it's full diyat.
