Re: Concept of Blood money
In Quran there are ayahs that tell Muslims that in crime of physical injury one should follow law of equal retaliation (Qisas), but if acceptable to grieved party than financial or any other type of compensation (Diya) is possible without going through retaliation. The relevant ayahs are:
Ayahs in Quran are:
2:178 (Yusuf Ali): O ye who believe! the law of equality is prescribed to you in cases of murder: the free for the free, the slave for the slave, the woman for the woman. But if any remission is made by the brother of the slain, then grant any reasonable demand, and compensate him with handsome gratitude, this is a concession and a Mercy from your Lord. After this whoever exceeds the limits shall be in grave penalty.
5:45(Yusuf Ali): We ordained therein for them: "Life for life, eye for eye, nose or nose, ear for ear, tooth for tooth, and wounds equal for equal." But if any one remits the retaliation by way of charity, it is an act of atonement for himself. And if any fail to judge by (the light of) what Allah hath revealed, they are (No better than) wrong-doers.
Now, as you can see, equal retaliation (Qisas) is right of grieved party … and compensation is only possible IF and only IF grieved party is willing to forgo retaliation (Qisas) and accepts compensation (Diya) in its place (and that also is allowed as mercy from Allah).
Above ayahs do not differentiates between intentional or unintentional inflicted injuries, neither specified compensation, thus leaving all this on grieved party concerned and government of the time.
Above is shariah law.
Anyhow, Islamic laws that developed over time, using above principle, at various places and period, is that, regimes enforced compensation (Diya) through courts. In enforcing ‘Diya’ governments also specified financial compensation for different injuries, taking into account intentional, unintentional and severity of injuries (unfortunately, at places, governments also took into account nature of grieved party when determining compensation … that is taking into account religion, nationality and other variables of grieved party). The reason for specified compensation could be that compensation does not become un-realistic, un-natural, and un-affordable.
Nevertheless, as one can see from Quranic ayah, acceptance of compensation or demanding retribution is right of grieved party, and by law, they should have this right especially if injuries inflicted are intentional … and if grieved party is not given this right by government (however limited in nature), especially for intentional injuries, than that (in my opinion) is wrong.
Note: In Islam, if there are valid justifiable reasons that are also acceptable following principles given in Quran, then governments can enact and enforce laws.
Thus, if governments do not make accepting fixed compensation as law than rich would always going to go for retribution (especially against poor who cannot compensate reasonably) and poor would most likely going to accept compensation from rich (especially when rich would keep increasing compensation) … and that would be unjust.
So fixed and enforced compensation in many ways is preferable option government adopts, that is acceptable using Quranic principle ... as compensation (Diya) is mentioned in Quran that Allah likes better than retribution and called that 'concession and a Mercy' from Allah.
