Abstract: Dieh means beautiful in Farsi. In case of wrongful suicide, the men of the criminal's paternal family give the ransom to the victim's family on his behalf. Diyeh is actually a cash fine and financial compensation, which has both a criminal aspect and a civil liability. If the crime is a mistake, first of all, it is the responsibility of the person to pay for it. Tolerating the payment of dowry on the part of Aqila Jani is similar to the insurance law at this time and keeps the spirit of cooperation and assistance in solving problems alive in Muslims.Machine summary: Some scientists believe that this law is a type of compulsory insurance, not optional and free insurance, and it has advantages because it is mutual protection; That is, each member of the family is responsible for the wrongful killing of each other and will provide mutual support on behalf of each other, on the other hand, the same people inherit from each other, and perhaps the fact that the inheritance share of men is twice as large is due to such issues. . Of course, there are many narrations about wrongful suicide and the wise responsibility of giving it to the victim's family, some of which will be reviewed.Consensus is another proof of the obligation of money in killing oneself, which Sahib Javaher cited in the beginning of the Book of Dayat in justifying taking money [Najafi 42:2]. Is the verdict of murder an obligatory or conditional error? According to the evidence of Aqila's guarantee, some scholars are of the opinion that the obligation to pay the ransom on behalf of Aqila is not a legal order.So that if there was no wise person or if he was unable to pay it, the guardians of the deceased could not refer to the murderer himself, rather, it is an obligatory sentence, and in fact, the person himself is the true guarantor [Georji, Vol. 2: 264]. From the summation of the evidences, we must say that the ransom is primarily the responsibility of the murderer, but as a duty, it has become obligatory on the wise to pay it on behalf of the soul to the parents of the deceased.
