Is it true that the expenses for treating an injured eye are not paid to the affected person, due to the absence of a legal text that obliges their payment, in an incident that led to the loss of one eye and a ruling of half the blood money (Diyya)?

The perpetrator of an accidental injury to one eye is liable for half the blood money, because the Prophet, peace and blessings be upon him, said: "And for one eye, fifty camels." As for the expenses of treatment and the doctor's fees, these are not obligatory upon the perpetrator in crimes for which a specific compensation has been legislated; rather, he is only obliged to pay what has been legislated.
