Is it permissible for Islamic countries to amend the amounts of diyah (blood money) according to rising prices and living costs, and to consider the amendment applicable to subsequent incidents, taking into account that the origin of diyah is camels, and what is estimated in money is their value, and that the ruling for diyah should be based on its value at the time the judgment is issued, not at the time of death?

The amount of Diyah (blood money) is one hundred camels, or one thousand gold dinars, or twelve thousand silver dirhams. Scholars have differed on whether gold and silver are independent standards that do not change with the fluctuations in the camel market—this is the view of the majority—or whether they are a substitute for camels, which is the preferred view of Ibn Hazm and Al-Shafi'i in his later opinion. If camels are the primary standard, then the perpetrator is required to provide one hundred camels. If he wishes to pay the Diyah with their equivalent value, he should pay their value at the time of payment. However, if gold and silver are independent standards, then the perpetrator is required to pay the specified amount in gold or silver at the time of payment, or its equivalent in current currencies.
