Qisas means retaliation or retribution in Muslim Law. It is the right of the victim or the victim's family to seek revenge against the offender for a crime committed.

The purpose of Qisas in Muslim Law is to prevent future crimes, deter criminals, and provide justice to the victim.

For Qisas to be applicable in Muslim Law, the crime must be intentional, a major crime, and the offender must be sane.

The procedure for Qisas in Muslim Law involves the victim or the victim's family filing a complaint with the authorities, the authorities investigating the complaint and determining if Qisas is applicable, and if Qisas is applicable, the offender will be punished accordingly.

Diyat in Muslim Law refers to compensation paid by the offender to the victim or the victim's family for a crime committed.

The purpose of Diyat in Muslim Law is to provide financial assistance to the victim or the victim's family, deter criminals, and promote reconciliation between the offender and the victim.

For Diyat to be applicable in Muslim Law, the crime must be unintentional, a minor crime, and the offender must be sane.

The procedure for Diyat in Muslim Law involves the victim or the victim's family filing a complaint with the authorities, the authorities investigating the complaint and determining if Diyat is applicable, and if Diyat is applicable, the offender will be ordered to pay compensation to the victim or the victim's family.

The difference between Qisas and Diyat in Muslim Law is that Qisas is retaliation while Diyat is compensation, Qisas is applicable for major crimes while Diyat is applicable for minor crimes, and Qisas is applicable for intentional crimes while Diyat is applicable for unintentional crimes.

Qisas and Diyat can be waived in Muslim Law by the victim or the victim's family.

Qisas and Diyat are important principles of Islamic criminal law, they help to maintain peace and order in society, and they promote justice and fairness.

In modern Muslim societies, Qisas and Diyat are implemented in a combination of traditional Islamic law and the laws of the country.

Some of the challenges in implementing Qisas and Diyat in modern Muslim societies include the conflict between traditional Islamic law and the laws of the country, the lack of consensus among Muslim scholars on the interpretation of Qisas and Diyat, and the difficulty in determining the appropriate amount of Diyat.

Some of the proposed reforms to Qisas and Diyat in Muslim Law include abolishing Qisas and Diyat, restricting Qisas and Diyat to certain crimes, and making Qisas and Diyat more flexible.

The future of Qisas and Diyat in Muslim Law is uncertain. It is possible that they will continue to be implemented in accordance with traditional Islamic law, that they will be abolished or restricted in scope, or that they will be reformed to make them more compatible with modern society.
