The amount of compensation is based on the percentage of responsibility. Blood money is to be paid not only for murder, but also in the case of unnatural death, interpreted to mean death in a fire, industrial or road accident, for instance, as long as the responsibility for it falls on the accused. The diyah compensation amount depends on the religion of the victim.
Human Rights Watch and United States’ Religious Freedom Report note that in sharia courts of Saudi Arabia, “The calculation of accidental death or injury compensation is discriminatory. In the event a court renders a judgment in favor of a plaintiff who is a Jewish or Christian male, the plaintiff is only entitled to receive 50 percent of the compensation a Muslim male would receive; all other non-Muslims (Buddhists, Hindus, Jains, Sikhs, Animists, Atheists) are only entitled to receive one-sixteenth of the amount a male Muslim would receive”.
While Saudi judges have the last say in any settlement, as of 2011, diya price for a Muslim man, in Saudi Arabia, was SR300,000 ($80,000) for an accidental death and SR400,000 ($106,666) in premeditated murder. (The price was raised that year due to a rise in the price of camels.)
Diyah in Saudi has been controversial, as in a 2013 case, where a father molested and murdered his five-year-old daughter, but avoided jail by paying money to her mother.
